Er:KYW crystals «In Stock»

Er³⁺:KYW are promising laser material for eye-safe emission at wavelength of 1609 nm, which can be resonantly diode-pumped into the upper laser manifold at 1534 nm. Due to low quantum defect high-slope efficiencies of >80% can be achieved with direct fiber laser or InGaAs/InP pumping. Because of broad and smooth emission in spectral range of 1570 - 1630 nm mode-locked “eye-safe” laser can be realized.
