KTiOPO_4 electro-optical devices with extinction ratio up to 1:1000

摘要

We report on a complete technology ensuring fabrication of reliable electro -optical modulator employing Russian flux grown KTiOPO_4 The pilot units employing 2- crystals thermally compensated scheme, with aperture 4*4 mm~2, operate at 1.064 mkm both at AC and DC mode and exhibit at half- wave voltage about 1500V an extinction ratio up to 1: 1000. No electrochromic damages were observed during multi hour testing.
