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.
We numerically solve the transfer equations of the extracavity silicon Raman laser to show that a silicon waveguide Mid-IR Raman laser is possible with a pumping power on the order of a few Watts. Considering the situation of the pumping wavelength at 2.94μm achievable using an Er:YAG laser and Raman laser wavelength at 3.47μm with the 521cm-1 Raman shift, the output characteristics of the silicon...
A rate-equation-based model is established to describe the behavior of an intracavity optical parametric oscillator (OPO) pumped in an actively -switched Raman laser system. The intracavity photon densities and the initial population inversion density are assumed to be Gaussian distribution. These coupled rate equations are solved numerically. In the experiment, a laser diode end-pumped acousto-optically...
A diode-pumped passively Q-switched Nd:YAG/BaWO4/KTP yellow laser is presented for the first time. The obtained maximum average output power, conversion efficiency, pulse energy were 1.21 W, 9.06%, and 68.5 μJ, respectively.
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 %.
