Lithium Iodate
(LiIO3) crystal is an uniaxial non-linear crystal with
high non-linear optical coefficients and wide transparency range. It
is used for frequency doubling of the low and medium power Ti:Sapphire,
Alexandrite and other lasers. In some cases it is used for frequency
doubling and -tripling of Nd:YAG lasers and auto-correlators to measure
ultra-short pulse width.
APPLICATIONS:
• From the second to forth harmonic generations of
the fundamental laser emission in the range from 690 to 2000 nm
• Optical parametric oscillation, obtaining of the tuned radiation in the ranges from 800 to 4000 nm
• Frequency multiplication and mixing in transparency crystal range from 280 to 5500 nm
• Measurement of parameters of ultra-short laser pulses
including the single ones
• Visualisation of IR radiation to obtain the object image by non-linear optical methods
We supply as-cut blanks up to 100 x 100 x 100 mm3, as well as optical elements made according to customer's order. |

The surfaces of LiIO3 crystals can be easily moistened.
Customers should be very careful in the maintenance of crystal surfaces.
The sealed housing is recommended for these crystals.
