Abstract | The lateral lasing of vertical external cavity surface emitting laser(VECSEL)is the key to restrict its high performance. We designed a gain chip structure with a large mismatch(30 nm)between the quantum well gain peak and the surface cavity mode at room temperature,and confirmed that this structure can effectively suppress the lateral lasing enhancement of VECSEL when the pump power increases. When the substrate temperature of the gain chip is 20 ℃,the longitudinal lasing wavelength of VECSEL is 980 nm and the lateral lasing wavelength is 950 nm. As the pump power increases gradually,the lateral lasing intensity decreases rapidly with the emergence of longitudinal lasing. This is because the stimulated radiation level of the quantum well matches the longitudinal lasing laser mode when the laser is longitudinal lasing. The longitudinal lasing laser mode can obtain higher mode gain and have an advantage in the competition with the lateral mode. When the substrate temperature is controlled at 0 ℃ and 10 ℃ ,the mismatch between the quantum well intrinsic gain peak and the surface cavity mode increases. At this time,VECSEL still shows a stable lateral lasing suppression effect. © 2023 Chines Academy of Sciences. All rights reserved. |
