4.5 [mu]m wavelength vertical external cavity surface emitting laser operating above room temperature
M. Rahim, A. Khiar, F. Felder, M. Fill, and H. Zogg
A midinfrared vertical external cavity surface emitting laser with 4.5 [mu]m emission wavelength and operating above room temperature has been realized. The active part consists of a single 850 nm thick epitaxial PbSe gain layer. It is followed by a 2 1/2 pair PbEuTe/BaF Bragg mirror. No microstruc ... [Appl. Phys.
