13 Mar 2009 EKSMA OPTICS offers large size DKDP crystals for frequency conversion of high energy Q-Switched lasers. Relatively low growth expenses of DKDP crystals and fast growth process makes DKDP cost effective solution for the high energy Q-switched lasers where large diameter beams - 10 mm and more are typical.
High energy pulses require preparation of surface quality to better than 10/5 scr/dig MIL standard and good flatness - exceeding lambda/4 or lambda/6 at 633 nm.
EKSMA OPTICS offers surface polishing quality better than 10/5 scr/dig and flatness better than lambda/6 of DKDP crystals with clear apertures up to dia 20 mm. However DKDP crystals with apertures up to 70x70 mm are available for special applications in very high energy lasers.
