It transmits from 190 nm to 3500 nm and is used for the second, third, fourth and fifth harmonics of Nd:YAG lasers, including 5HG at 213 nm, as well as for frequency doubling of ultrafast lasers. Its electro-optic coefficient also makes it suitable for Pockels cells and EO Q-switches.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wq-pdp__lbtek-tips\"\u003e\n\u003ch3\u003eKey
