Er:YAG crystals «In Stock»
Er3+:YAG crystal is an attractive laser material for eye-safe emission at wavelengths of 1617 and 1645 nm which can be resonantly diode-pumped into the upper laser manifold at 1470 nm and 1532 nm. Due to the low quantum defect, high slope efficiencies of >80% can be achieved with direct fiber laser or InGaAs/InP pumping. By using heavily erbium-doped (~50 at.%) YAG crystal efficient CW laser operation at ~3 µm can be obtained.
