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.

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:

Ti3+ (1.5-2 cm-1),
- 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.
