980 nm compact optical isolators using Cd _{1– <i>x</i> – <i>y</i>} Mn <i> _x </i> Hg <i> _y </i> Tesinglecrystals for high power pumping laser diodes

Abstract

The authors have developed compact optical isolators operating at 980 nm wavelength with an insertion loss of 1.0 dB, isolation of 30 dB, size of 4phis × 4.5 mm and endurance against laser power of ~500 mW using Cd1–x–yMnxHgyTe single crystals for the first time.
