Paper Abstract

We demonstrated laser diode pumped quasi-continuous-wave random laser in Nd3+ doped YAG nanopower with a one-mirror structure. Beside usual phenomena associated with laser, like threshold behavior and substantially narrowing of emission spectra, chaotic pulsing behavior was observed above a certain pumping level, which is explained as disturbed relaxation oscillation in random cavities. Possible relation between random lasing in such one-mirror structure and coherent backscattering effect, which is also referred as weak localization, is discussed with much interest.
