Abstract

We report on a complete technology ensuring fabrication of reliable electro-optical modulator employing Russian flux grown KTiOPO₄. The pilot units employing 2-crystals thermally compensated scheme, with aperture 4*4 mm², 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 electro chromic damages were observed during multi hour testing.
