Abstract :
The power control and the laser noise of a diode-pumped solid-state laser with increased intracavity power is investigated. An electrical spectrum analyser is employed to monitor the laser output of the system; wherein two kinds of dynamics are observed: (i) a stable operation when the laser emits more than 15 mW of UV power and (ii) a "green noise" like operation when many oscillating modes appear. Results also show that the oscillating modes can be controlled through the amplifier and the nonlinear crystal temperature.
