Abstract
An efficient intracavity frequency-doubled diamond Raman laser output at 620 nm wavelength is demonstrated. Laser output power of 750 mW at central wavelength of 620.1 nm was achieved successfully at a repetition rate of 2 kHz. The optical conversion efficiency was up to 11.0%. The laser beam M2 factors were less than 1.6 and 1.3 in the x and y directions, respectively. This intracavity diamond Raman laser offers a new way towards generating efficient pulsed Raman red laser.
