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:
        - Brewster shape, etc.
        - mirrors, output coupler, dichroic, etc. coatings

Nd:YVO. High efficient, widely used material for diode pumped lasers.
   Standard range:
        - doping level - 3% wt Nd3+, a-cut
        - dimensions - square or round diameter 1-3 mm, length 0-10 mm,
        - finish - 10/5 scr/dig, L/10, 30", AR<0.2%,
    Options:
        - Brewster shape, etc.
        - mirrors, output coupler, dichroic, etc. coatings

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:
        - doping level - 0.1% wt 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.
