The FDSS532-Q laser series, like all CryLaS pulse lasers with microchip as resonator, belongs to the family of diode-pumped solid-state (DPSS) lasers with passive Q-switching. The compact housing, combined with relatively high pulse power makes the lasers a suitable light source for applications where high energies with short pulse durations are required with minimal housing dimensions.
A diode-pumped microchip consisting of a resonator (Nd:YAG crystal) and a saturable absorber (Cr:YAG) bonded to it serves our lasers for beam generation. Starting from the 1064 nm fundamental wave, NLO optics (non-linear optics) are used to generate frequency multiples of this fundamental wave, and in some cases combine them, so that we can generate a wide range of laser wavelengths.
In contrast to CryLaS lasers at 213 nm, 266 nm, 355 nm and 1064 nm, the Q, MOPA and High Power lasers at 532 nm are in the visible spectral range (400 nm to about 750 nm). This green light is well perceived by the human eye, which is the reason for exploiting the generally good visibility of green laser light. Often this type of laser is used as a marking laser in construction or in medicine during operations. On the other hand, the lasers are suitable for ablation of biological material. This includes, but is not limited to, LIBS on gemstones or other materials that strongly absorb 532 nm. By having only one conversion stage between 1064 nm and 532 nm, our green Q lasers are capable of emitting comparatively high pulse energies.
Our pulsed, passively Q-switched microchip laser systems are suitable for use in industry (OEM) and scientific research due to their polyvalence. We are able to produce five different wavelengths from IR to DUV for our pulsed lasers:
- 1064 nm
- 532 nm
- 355 nm
- 266 nm
- 213 nm
