Diode Pumped

By using laser-diode as pumping source, a passively Q-switched Nd:YVO4laser with Cr4+:YAG saturable absorber is realized. Considering the Gaussian distribution of the pump beam and the oscillating laser intensity, the coupled rate equations of a LD-pumped passively Q-switched laser with Cr4+:YAG saturable absorber are given. The relations between the pulse width and the pump beam radius in the gain medium as well as the laser beam radius in the saturabe absorber are obtained from the numerical solutions of rate equations, and the theoretical calculations agree with the experimental results.

Probe Measurements

AbstractOptical pump-probe measurements were performed on planar slab waveguides containing silicon nanocrystals in an attempt to measure optical gain from photo-excited silicon nanocrystals. Two experiments were performed, one with a continuous-wave probe beam and a pulsed pump beam, giving a time resolution of approximately 25 ns, and the other with a pulsed pump and probe beam, giving a time resolution of approximately 10 ps. In both cases the intensity of the probe beam was found to be attenuated by the pump beam, with the attenuation increasing monotonically with increasing pump power. Time-resolved measurements using the first experimental arrangement showed that the probe signal recovered its initial intensity on a time scale of 45-70 μs, a value comparable to the exciton lifetime in Si nanocrystals. These data are shown to be consistent with an induced absorption process such as confined carrier absorption. No evidence for optical gain was observed.
