980 nm compact optical isolators using Cd1-x-yMnxHgyTe single crystals for high power pumping laserdiodes

The author have developed compact optical isolators operating at 480 nm wavelength with an insertion loss of 1.0 dB, isolation of 30 dB, size of 4φ×4.5 mm and endurance against laser power of ~500 mW using Cd_1-x-yMn_xHg_yTe single crystals for the first time
