Diode-pumped Solid-state Laser - Comparison To Diode Lasers
... DPSS and diode lasers are two of the most common types of solid-state lasers ... DPSS lasers generally have a higher beam quality and can reach very high powers while maintaining a relatively good beam quality ... As DPSS crystals are not 100% efficient, some power is lost when the frequency is converted ...
Diode-pumped Solid-state Laser - Common DPSS Processes
... The most common DPSS laser in use is the 532 nm wavelength green laser pointer ... Green DPSS lasers are usually around 20% efficient, although some lasers can reach up to 35% efficiency ... In other words, a green DPSS laser using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light ...
Laser Pointer - Colors and Wavelengths - Blue
... such as 473 nm usually have the same basic construction as DPSS green lasers ... These were DPSS type frequency-doubled devices ... the claimed-power of "laser pointer" products also includes the IR power (in DPSS technology only) still present in the beam (for reasons discussed below ...
Hazards - Infrared Hazards of DPSS Laser Pointers
... At such power levels, an IR filter for a DPSS laser may not be required as the infrared (IR) output is relatively low and the brightness of the visible wavelength of the laser will cause the eye to react (blink ... However, higher-powered (> 5 mW) DPSS-type laser pointers have recently become available, usually through sources that do not follow laser safety ... pointers, and usually lack the IR filters found in professional high-powered DPSS lasers, because of costs and additional efforts needed to accommodate them ...
