1. A laser device comprising:
a pump source; a ring resonator; a gain medium disposed in the ring resonator, the gain medium configured to receive radiation from the pump source and generate laser radiation; an optical diode disposed within the ring resonator to cause unidirectional propagation of the laser radiation; a passive Q-switch disposed within the ring resonator; and a three-dimensional holographic grating output coupler incorporated in the ring resonator, the three dimensional holographic grating output coupler being a narrow-band, reflective thick Bragg grating element configured to transmit the laser radiation at a predetermined wavelength.
