“…Efficient Cr,Nd:YAG self-Q-switched lasers have also been achieved with high peak power and short pulse width [5][6][7][8]. Besides PPLN and LBO crystals used in passively Q-switched intracavity frequency doubled green lasers [9,10], KTP crystal is widely used in the second harmonic generation because of its high optical damage threshold, large acceptance angles and thermally stable phase-matching properties [11][12][13][14]. Laser-diode (LD) pumping KTP intracavity frequency doubled Cr,Nd:YAG self-Q-switched and mode-locked green lasers have been demonstrated [15].…”

Stable, enhanced intracavity frequency doubled Cr,Nd:YAG self-Q-switched miniature green laser with gray tracking resistant KTP (GTR-KTP) crystal has been demonstrated at room temperature. The maximum average output power of 1.2 W at 532 nm was achieved at the absorbed pump power of 7 W, and the corresponding optical-to-optical efficiency was 17%. Laser pulses with a pulse energy of 16 µJ and peak power of 1.3 kW were achieved. The laser operated from 6.7 kHz to 75 kHz with the absorbed pump power. Near-diffraction-limited laser beam quality with M 2 less than 1.5 was obtained. The stable laser operation was achieved with less than 3% fluctuation of the average output power within 2 h.

The highly efficient performance of a Cr,Nd: YAG/KTP intracavity frequency doubled self-Q-switched miniature green laser is demonstrated at room temperature. The average output power of an over-1-W green laser at 531.5 nm is obtained at the absorbed pump power of 7.3 W. The slope efficiency and optical-to-optical efficiency are as high as 22.2% and 13.7%, respectively. The laser pulses with pulse width less than 6 ns, pulse energy of 12 µJ, and peak power of over 2 kW are achieved. The laser works from several to 76.5 kHz, depending on the pump power levels. A near diffraction limited laser beam with M 2 less than 1.5 is achieved in this miniature green laser.Index Terms-Cr,Nd:YAG, intracavity frequency doubled, laser-diode pumped, miniature lasers, self-Q-switched lasers.
