Advantage:
- Large nonlinear optical and electro-optical coefficients
- Wide angular bandwidth and small walk-off angle
- Broad temperature and spectral bandwidth
- Low dielectric constants, loss tangent and ionic conductivities (much less than that of KTP)
- High damage threshold
- Lower absorption and high transmission in the 3-4 µm spectrum range than KTP.
- Highly resistant to high intensity laser radiation.
