What does laser stand for?
- A.
Light Amplification by Stimulated Emission of Radiation
- B.
Long Amplification by Simulated Emission of Radiation
- C.
Light Acceleration by Stimulated Emission of Radiation
- D.
Light Amplification by Stipulated Emission of Radiation
Correct Answer
A. Light Amplification by Stimulated Emission of RadiationExplanation
The correct answer is Light Amplification by Stimulated Emission of Radiation. This is the full form of the term "laser." A laser is a device that emits a focused beam of light through the process of stimulated emission. The term "amplification" refers to the process of increasing the intensity or power of the light, and "stimulated emission" refers to the process by which photons are emitted from excited atoms or molecules. Therefore, the correct answer accurately describes the principles behind the functioning of a laser.Rate this question:
-

For laser light generation one needs at least?
- A.
Amplifier and q-switch
- B.
Pump energy, resonator and laser medium
- C.
Laser medium, q-switch and pump energy
- D.
Pump energy, aperture and laser medium
Correct Answer
B. Pump energy, resonator and laser mediumExplanation
To generate laser light, three essential components are required: pump energy, resonator, and laser medium. The pump energy is needed to excite the atoms or molecules in the laser medium, raising them to a higher energy state. The resonator provides the necessary feedback to create a coherent beam of light by reflecting the photons back and forth through the laser medium. Finally, the laser medium itself is the material that emits the laser light when stimulated by the pump energy. Therefore, all three components are necessary for laser light generation.Rate this question:

End-pumped lasers are used because of?
- A.
Low cost
- B.
Simple design
- C.
Every diode pumped laser is end-pumped
- D.
Better beam quality
Correct Answer
D. Better beam qualityExplanation
End-pumped lasers are used because they offer better beam quality. This means that the laser beam produced by an end-pumped laser is more focused and has a higher spatial coherence compared to other types of lasers. This is important in applications where a high-quality, precise laser beam is required, such as in laser cutting, laser engraving, and scientific research. By using end-pumping, the laser system can achieve a more efficient energy transfer and produce a beam with improved characteristics, resulting in better overall performance.Rate this question:

A Vanadate laser with frequency tripling generates the following wavelength?
- A.
355nm
- B.
532nm
- C.
1,064nm
- D.
365nm
Correct Answer
A. 355nmExplanation
The correct answer is 355nm. A Vanadate laser with frequency tripling refers to a type of laser that uses a Vanadate crystal to generate laser light. Frequency tripling is a process where the laser light's frequency is tripled, resulting in a shorter wavelength. In this case, the wavelength generated is 355nm, which falls within the ultraviolet range of the electromagnetic spectrum.Rate this question:

If one needs a long depth of focus one should choose?
- A.
Fiber laser over a Nd-YAG laser
- B.
Long focal length and long wavelength
- C.
Good beam quality with a short focal length
- D.
IPG over a TRUMPF fiber
Correct Answer
B. Long focal length and long wavelengthExplanation
A long depth of focus refers to the ability of a lens or laser system to maintain focus over a larger range of distances. In this case, choosing a long focal length and long wavelength would be the best option. A longer focal length allows for a larger depth of focus, while a longer wavelength increases the diffraction limit, resulting in a larger depth of focus as well. This combination ensures that the laser beam remains focused over a greater distance, making it suitable for applications where a long depth of focus is required.Rate this question:

For some plastics a UV laser is advantageous. Why?
- A.
Plastics evaporate better with a UV laser
- B.
UV laser reflects better on plactics than infra-red
- C.
Absorption of 355nm wavelength is higher than 1,064nm
- D.
Plastics are designed to be marked with a UV laser
Correct Answer
C. Absorption of 355nm wavelength is higher than 1,064nmExplanation
The absorption of a UV laser with a wavelength of 355nm is higher than that of an infra-red laser with a wavelength of 1,064nm. This means that the UV laser is more effective in transferring energy to the plastics, resulting in better marking or processing.Rate this question:

Why is a Nd-YAG better suited to mark metals than a CO2 laser?
- A.
Nd-YAG laser has a higher average power
- B.
CO2 lasers are more expensive than Nd-YAG
- C.
CO2 lasers have bigger spot size which results in bigger mark fields
- D.
On metals Nd-YAG lasers have better absorption than CO2
Correct Answer
D. On metals Nd-YAG lasers have better absorption than CO2Explanation
Nd-YAG lasers are better suited to mark metals because they have better absorption on metal surfaces compared to CO2 lasers. This means that the Nd-YAG lasers are able to transfer more energy to the metal, resulting in a more effective and precise marking. The higher absorption of Nd-YAG lasers on metals makes them a preferred choice for marking applications on metal surfaces.Rate this question:

On plastics a photochemical effect can take place using a laser with a wavelength of?
- A.
355nm
- B.
532nm
- C.
1,064nm
- D.
1,062nm
Correct Answer
A. 355nmExplanation
Plastics can undergo a photochemical effect when exposed to a laser with a specific wavelength. In this case, the correct wavelength is 355nm. This specific wavelength is absorbed by the plastic material, causing it to undergo a photochemical reaction. The other wavelengths mentioned (532nm, 1,064nm, and 1,062nm) are not the optimal wavelengths for inducing a photochemical effect in plastics.Rate this question:

Which of the following statements for the IPG fiber laser is correct?
- A.
Can run at higher frequencies than a TRUMPF fiber
- B.
Resonator contains a Q-switch
- C.
Has a better beam quality than a TRUMPF fiber laser
- D.
Design is fully monolithic
Correct Answer
B. Resonator contains a Q-switchExplanation
The correct answer is "Resonator contains a Q-switch." A Q-switch is a device used to control the output of a laser by rapidly switching the laser cavity between a high-Q (high quality factor) and a low-Q state. This allows for the generation of short, high-energy pulses of laser light. The presence of a Q-switch in the resonator of an IPG fiber laser indicates that it is capable of producing high-energy pulses, making the statement correct.Rate this question:

10
Correct Answer
B. 1Explanation
The best beam quality that can be theoretically achieved is 1. This indicates that the beam is perfectly focused and has the smallest possible divergence angle, resulting in a highly concentrated and well-defined beam. A value of 1 signifies an ideal beam quality with minimal distortion or spreading.Rate this question:

What is the big advantage of a beam stirred laser marking system over laser marking with a mask?
- A.
Low price
- B.
Very fast laser marks
- C.
Both technologies are more or less equal in performance
- D.
Flexibility and large mark fields
Correct Answer
D. Flexibility and large mark fieldsExplanation
A beam stirred laser marking system offers the advantage of flexibility and large mark fields compared to laser marking with a mask. This means that the beam stirred system allows for greater versatility in marking different types of materials and products, as well as the ability to create larger and more complex marks. In contrast, laser marking with a mask may be limited in terms of the size and variety of marks that can be produced. Therefore, the flexibility and large mark fields provided by the beam stirred system make it a preferable choice for many applications.Rate this question:
-
- 23.
To achieve a large mark field one need?
- A.
Long focal length
- B.
Small wavelength
- C.
Small scanner mirrors
- D.
A fiber laser
Correct Answer
A. Long focal lengthExplanation
A long focal length is needed to achieve a large mark field. A longer focal length allows for a larger area to be focused on, resulting in a larger mark field. By increasing the distance between the lens and the object being marked, the focal length increases, allowing for a larger mark field to be achieved.Rate this question:

- A.
A MOFPA fiber laser contains a q-switch
- B.
All fiber lasers contain at least one amplifier
- C.

Correct Answer
B. All fiber lasers contain at least one amplifierExplanation
All fiber lasers contain at least one amplifier. This statement implies that amplifiers are a necessary component in all fiber lasers. Amplifiers are used to increase the power of the laser beam by amplifying the light signal. Therefore, it can be concluded that all fiber lasers require at least one amplifier for their operation.Rate this question:
