Low-threshold monomode ion-exchanged waveguide lasers in neodymium-doped BK-7 glass

摘要

Waveguide lasers have been fabricated by potassium ion-exchange in neodymium-doped BK-7 glass. Lasers operating at lambda =1058 nm in a single-transverse-mode at both pump and lasing wavelengths showed launched-power thresholds as low as 7.5 mW.
