Fig. 1. Schematic of the free-running SLM diamond Raman laser. HR, high reflectivity mirror; HWP, half-wave plate; LP1200, long-pass filter cut at 1200 nm; BS, beam splitter; PM, power meter; FPI, scanning Fabry–Pérot interferometer.
Fig. 2. (a) The powers of the Stokes output (red spot) and residual pump (blue square) as a function of pump power. The inset is the Stokes beam profile at the maximum output power. (b) Long-term power stability of pump and Stokes output for 1 hour.
Fig. 3. (a), (c), (e) Plots of the spectral characteristics of Stokes outputs for different cavity lengths. (b), (d), (f) Plots of the FPI trace of Stokes outputs for different cavity lengths corresponding to (a), (c) and (e), respectively.
Fig. 4. The linewidth of (a) pump and (b) Stokes outputs in the free-running V-shaped DRL. The red solid lines represent Lorentzian fits to the experimental data.
Fig. 5. (a) Wavelength stability of the Stokes and pump outputs for 1 hour. (b) Four typical FPI traces of the SLM Stokes output after multiple acquisitions.
