Single-frequency 1178.3-nm laser lines are generated through crystalline Raman laser and amplifier, respectively. From Raman laser, pulse energy of 13.7 uJ is obtained with linewidth less than 130 MHz. From Raman amplifier, pulse energy of 26.7 mJ is realized with linewidth less than 500 MHz.
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...
