Laser Active Optics
Nd:YAG. Classic laser active material widely used for CW
and pulsed laser systems up to date. Good efficiency, high
homogeneity and very high thermal conductivity keep the material
still to be in use. Available Chokhralsky and horizontally grown for
lamp and laser diode pumping. Each sample wave front distortion
controlled by Mark-Zygo interferometer. Quality grades: selected
(SEQ, distortion Lambda/12 per inch), research (REQ, L/8/"),
industry (INQ, L/4/"), low (LOQ, L/2/"), all per diameter
of 6.3 mm and single pass.
Standard range:
- doping level -
0.7-0.9-1.1% wt Nd3+,
- dimensions - square or round diameter 1-10 mm, length 0-120 mm,
- finish - 10/5
scr/dig, L/10, 10", AR<0.2%,
Options:

Nd:YVO. High efficient, widely used material for diode
pumped lasers.
Standard range:

Ti:Sapphire. Already laser world standard broad band media
used in oscillators and amplifiers of widely tunable and ultra
short pulse systems, pulsed and CW.
Standard
range:

- dimensions - square or round diameter 1-15 mm, length 0-30 mm,
- finish - 10/5
scr/dig, L/10, 30", Brewster
Options:
- doping level - up to
0.5% wt Ti3+,
- plane
parallel shape, etc.
-
mirrors, output coupler, dichroic, etc. coatings
Cr4+ Passive Modulators. Used for passive Q-switching of
Neodymium laser oscillators. Compared to colored LiF crystals, these
are stable in time and temperature due to their absorbing centers
being regular dopants not induced grid defects. High thermal
conductivity of garnet hosts, especially of YAG, and high damage
threshold allows you to use the modulators for high average or peak
power lasers. High extinction coefficient makes typical thickness of
the modulators to be few millimeters.
Standard
range:
- host material
YAG
- initial
transmission 20%,
-
dimensions - square or round diameter 1-10 mm,
- finish - 10/5 scr/dig, L/10, 30", AR<0.2%
Options:
- host
material GSGG
-
initial transmission up to 95%,
- mirrors, output coupler, dichroic, etc. coatings
Also available Er:YAG, Nd:YAP, Nd:KGV and Forsterite - an attractive relatively new material offering tunable laser oscillation around 1300 nm - for wave guiding, air tracing, medicine and ultra short pulse generation.
