What does the acronym DPSS stand for?
Correct Answer
Diode Pumped Solid State
Diode Pump Solid State
Diode-pumped solid-stateExplanation
The acronym DPSS stands for Diode Pumped Solid State. This refers to a type of laser in which the active medium is a solid-state material that is pumped by a diode laser. The diode laser emits light that is absorbed by the solid-state material, causing it to become excited and emit laser light. This technology is commonly used in various applications such as laser pointers, laser engraving, and scientific research.Rate this question:

What is the ideal current of a pHR-803t laser diode?
- A.
30-40 mA
- B.
100-120 mA
- C.
180 - 200 mA
- D.
450 - 500 mA
- E.
1 - 1,2 A
Correct Answer
B. 100-120 mAExplanation
The ideal current for a PHR-803t laser diode is 100-120 mA. This range of current ensures that the laser diode operates within its optimal performance and efficiency levels. Going below or above this range may result in reduced output power or even damage to the diode. Therefore, it is important to maintain the current within the specified range for the proper functioning of the laser diode.Rate this question:

What type of laser emits light at 694.3 nm?
- A.
Ruby laser
- B.
DPSS laser
- C.
Helium-Neon laser
- D.
Argon-Ion laser
- E.
Diode laser
Correct Answer
A. Ruby laserExplanation
A Ruby laser emits light at a wavelength of 694.3 nm. This type of laser uses a synthetic ruby crystal as the gain medium, which is excited by a flash lamp or another laser. The ruby crystal produces a red laser beam due to the transition of chromium ions within the crystal. This specific wavelength makes the Ruby laser suitable for various applications, including dermatology, tattoo removal, and scientific research.Rate this question:

Which of these is a beam mode (Transverse mode) ?
- A.
Class 3B
- B.
TEM00
- C.
PE-00
- D.
Cubic
- E.
