Its broad phase-matching capability supports OPOs driven by several pump lasers: tuning over 2.5–12 µm has been obtained with a 2.05 µm Ho:YLF pump, and non-critical phase matching gives 1.9–5.5 µm output with 1.4–1.55 µm pumping. AGSe is also used for frequency doubling of CO2 lasers, and WaveQuanta supplies it with custom cuts and coatings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wq-pdp__lbtek-tips\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransparency range 0.73–18 µm;
