The rate equations are solved and the experiments are performed with a rotating prism Q-switched ruby laser with a CdS sample in its cavity. As predicted by the theory,the output intensity and output energy both are decreased and pulse length is increased as compared with the normal Q-switched case.展开更多
文摘Using internal by two-photon induced light absorption of semiconductor material to lengthen the pulses of Q-switched lasers is discussed. The rate equations are solved and the experiments are performed with a rotating prism Q-switched ruby laser with a CdS sample in its cavity. As predicted by the theory,the output intensity and output energy both are decreased and pulse length is increased as compared with the normal Q-switched case.
