This paper presents a tunable laser near 535 nm. It is obtained by the intracavity frequency doubling of the tunable Stokes laser emission based on the stimulated polariton scattering in MgO:LiNbO3 crystal. The tunable green laser wavelength range was from 534.8 nm to 536.9 nm. The maximum output energy at 535.7 nm was 4.48 mJ.
The characteristics of the simultaneous Q-switching and mode locking in an intracavity actively Q-swithched Raman laser in which an Nd:YAG is the gain medium and an SrWO4 is the Raman medium is investigated.
We have demonstrated a stable actively Q-switched and mode-locked (QML) YVO4-Nd:YVO4 laser by using an acousto-optic modulator as Q switch and a KLM as mode-lock modulator. From which the great average output power, the high efficiency are obtained. The nearly 100% modulation depth of the Q-switched mode-locked pulses can be obtained at any pump power over the threshold. The mode-locked pulse inside...
A diode-end-pumped actively Q-switched intracavity Raman laser with a ceramic Nd:YAG as the gain medium and a BaWO4 as the Raman medium is investigated. The obtained maximum conversion efficiency is 23.9 %.
The intracavity photon densities and the initial population inversion density were assumed to be Gaussian distributions in the rate equations of the laser diode end-pumped actively Q-switched intracavity Raman laser. These space-dependent rate equations were solved numerically. In the experiment, an efficient self-Raman laser was realized based on the multifunctional Nd:YVO4 laser crystal with the...
