| 英文摘要 | The dual-wavelength lasing from vertical external cavity surface emitting laserVECSEL is realized by the large gain spectra and cavity mode detuning and the stable external cavity is designed. The emission wavelength can be switched between single-wavelength lasing and dual-wavelength lasing according to our simulation results and three operation modes are proposed and proved by our experiments. The side-mode of VECSEL with side-mode wavelength appears when the pump power exceeds the threshold power. As the pump power is increased the rollover of output power can be observed on the power curve. However when the pump power is further increased the output power can be increased again which we called the second-threshold phenomenon. And the dual-wavelength lasing can be observed. The output power can reach 359 mW during the dual-wavelength lasing with the lasing wavelengths located at 954.2 nm and 1 001.2 nm. When the pump power exceeds the second threshold only one lasing wavelength of 1 002.4 nm can be observed and this wavelength is the cavity-mode wavelength. The laser spot behaves the circular symmetrical shape with Gaussian morphology at both the single-wavelength and dual-wavelength lasing. The divergence angle of VECSEL is increased from 5.9 to 7.9 which might be caused by the mode competition between the two modes. The dual-wavelength lasing of VECSEL from single gain chip proposed by us has great potential in the LiDAR and terahertz applications in the future. 2022 Chines Academy of Sciences.
