A novel transverse mode control resonator for pulsed Nd3+:YAG laser
It is presented in this letter that a novel transverse mode control resonator (TMCR) can be constructed by using a stable resonator in oonjuction with a suitable hollow circular dielectric waveguide. In comparison with a TMCR with a pinhole, the energy conversion of the pump to TEM00 mode output is high and the beam fan field divergence is small. The mechanism of the novel TMCR is discussed and analysed.
