Abstract

We describe a simple method of controlling the oscillating longitudinal mode of a diode-pumped-microchip green laser by changing injection currents to the laser diode. We observed the dependence of the oscillating longitudinal modes on the injection current and operation temperature in the microchip green laser, and demonstrated that the stable oscillating longitudinal-mode operation under the single mode, two and three modes can be achieved by only controlling injection currents from 850 to 1050 mA. The maximum output power of the microchip green laser as high as 105.5 mW was obtained under the single longitudinal-mode operation pumped by an 810 mW pumping power. The corresponding long-term power stability was better than 0.47 % for the measuring time interval of 12 hours.
