Advantage:
Cut-off wavelength up to 180 nm
Maximum FOHG and FIHG conversion efficiencies of Nd doped laser
Relatively large effective NLO coefficient (about two times that of KDP)
Wide acceptance angle and small walk-off angle
The VUV output at 193 nm is available by phase matching
No saturation for high-power generation
Short grow cycle and large size
