Abstract:

Spectral brightness of SRS radiation in lead vapor pumped with a broadband (two lines 3 cm–1 wide) and a narrowband (0.1 and 0.01 cm–1) XeCl laser radiation with the divergence close to the diffraction limit has been studied experimentally. It was revealed that SRS linewidth is Doppler limited. For a narrowband pump the SRS efficiency increases two times, and the SRS beam divergence determined by the beam energy within the diffraction angle is three to four times as large as that of the pump beam.
