Effective CW and quasi-CW LBO frequency doubled Nd:YAG lasers

Intracavity 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).

Extreme value statistics in quasi-CW Raman fiber lasers

It is found that rare extreme events are generated in a Raman fiber laser. The mechanism of the extreme events generation is a turbulent-like four-wave mixing of numerous longitudinal generation modes. OCIS codes: (190.4370) Nonlinear optics, fibers; (190.4380) Nonlinear optics, four-wave mixing Extreme type statistics in nonlinear fiber optics has attracted a great attention since the experime...

Chapter 5 CW DYE LASERS

Modeling of quasi-three-level lasers and operation of cw Yb:YAG lasers.

We present modeling studies of quasi-three-level laser oscillators, the validity of which was revealed by Ti:Al(2)O(3)-pumped Yb:YAG laser experiments, and these results are shown to be in excellent agreement with the theory. As much as 75% slope efficiency was obtained with a hemispherical laser cavity. Previous modeling calculations of laser performance have been valid only for certain specia...

Cw X-ray Preionized Pulsed Gas Lasers

We have successfully demonstrated that the cw x-ray generator can work as a preionization source for a pulsed H F laser. The preionization effect of cw x radiation was revealed by a comparative study of with and without applying x-ray photons to the H F laser. Since dose rate of the cw x-ray generator is easily controllable, the laser output could be measured as a function of initial electron n...
