摘要:Channel waveguide in Pr:YLF crystal is fabricated by emtosecond laser (fs-laser) micromachining system. The micro Raman (μ-Raman) spectra and scanning confocal fluorescence imaging investigations of the depressed cladding structure indicated that slight changes (with respect to widths of the emission lines and spectral positions) have been generated in the laser-modification region. The microphotoluminescence (μ-PL) experiment manifests an excellent preservation of the fluorescence properties of the Pr3+ ions in the guiding area. π-polarized waveguide laser at wavelength of 605 nm and 720 nm were achieved with a pumping laser at a wavelength of 444.5 nm. The maximum output power of the lasers achieved was 66 mW and 47 mW with slope efficiencies of 9.5% and 6.3%. © 2018 OSA.
