BBO. The crystals are useful for wave mixing in high power
laser
systems, especially effective generating into UV region up to 200 nm.
High
damage threshold and optical homogeneity, wide temperature bandwidth, 6
times greater than KDP nonlinearity are main advantages of the crystal.
Useful as active media in pulsed parametric oscillators. Available: up
to 10x12 mm aperture and 15 mm length, AR-coated.
LBO. The crystal useful for wave mixing and parametric
conversion
in high power pulsed and mode locked CW laser systems. Very high damage
threshold compensates lower nonlinearity of about three times of KDP
and
makes the crystal even more efficient in some applications like
frequency
doubling of mode locked CW Nd:YAG. Small walk-off, wide acceptance
angle,
unique non critical phase matching range makes it useful for
ultra-short
pulse and parametric laser systems. Available: up to 15x15 mm aperture
and 20 mm length, AR-coated.
AGS. The crystal (AgGaS2) useful for wave mixing in infrared
laser systems. High nonlinearity makes it one of the best choices to
extend
you laser system spectral range down to 11 micron spectral region.
Available:
up to 12x15 mm aperture and 15 mm length, AR-coated.
GaSe. The crystals useful for wave mixing in far infrared
laser
systems. Allows to extend you laser system spectral range down to 18
micron
spectral region. Available: up to 50 mm aperture and 20 mm length,
cleavage
cut, uncoated.
KDP, DKDP, LiIO3. Classic laser nonlinear crystals that
should
not be forgotten. Low price of KDP and very high nonlinearity of LiIO3
sometimes are the best choice. DKDP with 92-95% of Deuterium is widely
used as electrooptic material. Available: LiIO3 up to 30x30 mm aperture
and 30 mm length. KDP, DKDP - up to 30x30 mm aperture and 60 mm
length,
AR-coated.
KTP. The crystals are useful for optical wave mixing,
electrooptical
modulation, optical wave guiding. Besides high electro-optic
coefficients
have also low dielectric constant. Typically used for Type II doubling
of 1064 nm radiation in CW and quasi-CW laser systems at intensities up
to 180 MW/cm2 with efficiency exceeding
50% and more. Useful as active media in CW and quasi-CW parametric
oscillators. Available: up to 15x15 mm aperture and 20 mm length,
AR-coated.
