Wavelength tuning in cryogenically cooled lasers based on Er-doped orthovanadates

摘要

Continuous tuning between 1590 and 1612 nm has been demonstrated in cryogenically cooled lasers with composite active media consisting of Er: YVO4, Er: LuVO4, and Er: GdVO4 crystals resonantly pumped by a fiber-coupled laser diode emitting at 1529 nm. Wavelength tuning was implemented using an intracavity single-plate birefringent filter. (C) 2016 Optical Society of America
