- Crystal length from 0.1-30mm, size up to 15x15x30mm
- AR coating from visible to 3300nm
Potassium Titanyle Arsenate(KTiOAsO4), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, low dielectric constants. And its low ionic conductivities result in higher damage threshold compared with KTP.
Features
- Large NLO and E-O coefficients
- Wide angular bandwidth and small walk-off angle
- Broad temperature and spectral bandwidth
- Lower absorption in the 3-4um range than KTP
- High thermal conductivity
- High damage threshold
- Stable chemical and mechanical properties
- No hygroscopic susceptibility
Applicatons Notes
- Excellent for Optical Parametric Oscillation (OPO)
- Second Harmonic Generation – SHG@1.083um-3.789um
- Sum and Difference Frequency Generation (SFG and DFG)
- Electro-optical Q-switch and modulation
