InGaN-GaN Disk Laser for Blue-Violet Emission Wavelengths
An optically pumped InGaN-GaN surface-emitting laser with external cavity emitting at 393 nm has been realized. The peak output power is 300 W, the slope efficiency 3.5%, and the threshold pump power density 700 kW/cm 2 . Critical parameters in the design of the laser will be discussed and ways to i...
