High-Power Bottom-Emitting Vertical-Cavity Surface-Emitting Lasers under Continuous-Wave, Quasi-Continuous-Wave, and Pulsed Operation

The characteristics of high-power bottom-emitting vertical-cavity surface-emitting lasers (VCSELs) with an aperture of 500 μm are reported. The output power and the spectra of the device are measured at different injection currents under CW, quasi-CW, and pulsed operation. The maximum peak output po...

Zusammenfassung:The characteristics of high-power bottom-emitting vertical-cavity surface-emitting lasers (VCSELs) with an aperture of 500 μm are reported. The output power and the spectra of the device are measured at different injection currents under CW, quasi-CW, and pulsed operation. The maximum peak output power of 92 W is achieved at room temperature, which is, to the best of our knowledge, the highest value reported for a single device. The thermal effect under pulsed operation is far lower than that at the other two operation modes.
