Intracavity frequency-doubled degenerate laser.
We develop a green light source with low spatial coherence via intracavity frequency doubling of a solid-state degenerate laser. The second-harmonic emission supports many more transverse modes than the fundamental emission, and exhibits lower spatial coherence. A strong suppression of speckle formation is demonstrated for both fundamental and second-harmonic beams. Using the green emission for...
متن کاملA quasi - continuous superradiant Raman laser with < 1 intracavity photon
A Quasi-Continuous Superradiant Raman Laser with <1 Intra-cavity Photon Report Title Steady-state collective emission from ensembles of laser cooled atoms has been proposed as a method for generating sub-millihertz linewidth optical lasers, with potential for broad impacts across science and technology. We have built a model system that tests key predictions for such active oscillators using a ...
متن کاملDiode-pumped multi-frequency Q-switched laser with intracavity cascade Raman emission.
A diode-pumped actively Q-switched mixed Nd:Y(0.3)Gd(0.7)VO(4) laser with an intracavity KTP crystal is developed to produce cascade SRS emission up to the fourth order. With an incident pump power of 14 W and a repetition rate of 50 kHz, the average output powers at the first, second, third and fourth Stokes modes are approximately 0.05 W, 0.61 W, 0.25 W, and 0.11 W, respectively. The maximum ...
متن کاملIntracavity Frequency-Doubled and Frequency-Stabilized CW Ring Nd:YAP Laser.
A frequency-doubled and frequency-stabilized ring Nd:YAP laser with a six-mirror cavity is demonstrated. This laser satisfies both the thermal insensitivity and optimal frequency-doubling conditions. A second-harmonic output to 1 W at 0.54 mum is achieved. The intensity fluctuation is less than ?1.5% and the frequency stability is better than ?1 MHz (5 min).
متن کامل589 nm laser generation by frequency doubling of a single-frequency Raman fiber amplifier in PPSLT.
A high-power single-frequency 1178 nm continuous-wave laser is generated in a two-stage stimulated-Brillouin-scattering-suppressed all-polarization-maintaining Raman fiber amplifier pumped by 1120 nm fiber lasers. A polarization-extinction-ratio of 30 dB is achieved due to the all-polarization-maintaining configuration and the polarization dependence gain of Raman scattering. Single-pass freque...
