TRUMPF Technology Questions: Quiz!

TRUMPF's fiscal year starts on July 1st and ends on June 30th. This means that the company's financial reporting and accounting period spans from July to June of the following year.

TRUMPF is owned by a family. This means that the company is not publicly traded and does not have venture capitalists or a global investment company as owners. The fact that TRUMPF is family owned suggests that it is likely a privately held company, with ownership and control held within the family.

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.

The annual revenue of TRUMPF Inc., Farmington, CT (including US, MEX, CAN) in fiscal year 2008/2009 was $300 million.

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.

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.

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.

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.

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.

In fiscal year 2008/2009, 71% of the overall revenue of TRUMPF Inc. was generated directly or indirectly with laser technology. This means that laser technology played a significant role in the company's revenue generation during that period.

In fiscal year 2008/2009, the annual revenue of TRUMPF Group was $2.3 billion.

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.

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.

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.

The correct answer is Farmington, CT because it is mentioned in the given options as one of the locations from where spare parts for TruMark products are delivered in North America.

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.

TRUMPF was founded in 1923.

The TruMark products are developed and manufactured in Gruesch, Switzerland.

The TruMark Service Center is located in Plymouth, MI. This answer is correct because it directly states the location of the service center.

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.

The correct answer is 7,770. This suggests that at the end of the fiscal year 2008/2009, there were 7,770 employees working with the TRUMPF Group.

Ytterbium and Vanadate do not have the exact same wavelength.

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.

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.
