Demonstration of a diode-pumped dual-wavelength metastable krypton laser
Figures & Tables(8)
Fig. 2. Schematics of the experimental setup of a diode-pumped Kr* laser. BS, beam splitter; DM, dichroic mirror; OC, output coupler; LPF, long pass filter; PD, photodetector.
Fig. 3. Time-dependent number density of Kr* at different pressures.
Fig. 4. Spectrum of the output laser (877 and 892 nm) and the pump stray light (811 nm).
Fig. 5. Time-dependent traces for the voltage between two electrodes, the number density of Kr (1s5) under discharge only and the laser intensity under 7.6 W pump power.
Fig. 6. Laser power of the Kr* laser with increasing pressure, under 7.6 W pump power.
Fig. 7. (a) Population distribution in Kr (2p) (the error bar represents standard deviation) and (b) population of Kr (2p8, 2p9 and 2p10) versus pressure.
Fig. 8. Time-dependent traces of the number density of the 1s5 and 1s4 levels. (The oscillation in the figure is the noise of the discharge.)
