Abstract	Femtosecond-laser direct-write waveguide lasers are a significantly enabling technology in the fields of sensing, communications, defense and integrated quantum optics. We recently demonstrated distributed feedback (DFB) monolithic waveguide lasers with high output powers (of order 100 mW) and optical conversion efficiencies of 17% [1]. However for their general acceptance in the above fields, waveguide lasers need to have proven stability, lifetimes and resilience to changing external environmental conditions. The environmental sensitivity of integrated DFB or distributed Bragg reflector (DBR) waveguide-lasers is considerably greater than platforms based on amplifying waveguides and external gratings [2] because changes in the refractive index profile of the waveguide-Bragg grating (WBG) effect both the laser wavelength and the output power due to the changing reflectivity of the grating structures.
