Abstract :

Optically pumped semiconductor (OPS) laser has unique advantages over its electrically pumped counterparts. The most prominent one being power scalable without sacrificing the beam quality. Lasing in the fundamental frequency at near infrared with over 100 watts has been demonstrated. Visible power in tens of watts by second harmonic generation and ultraviolet power in several watts by third harmonic generation have been commercialized. In this work, an OPS gain model is developed based on the 8-band kp method. Theoretical and experimental result indicates that this model cans predict the threshold accurately. Temperature dependent simulation allows for the modeling of self-heating and thermal rollover, therefore predicting the achievable output power. Guided by this model, improvement of existing wavelength and expansion of the wavelength coverage are demonstrated.
