Optically pumped 1. 55-. mu. m double heterostructure Ga/sub x/Al/sub y/In/sub 1-x/-yAs/Al/sub u/In/sub 1-u/As lasers grown by molecular beam epitaxy
We report the first successful realization of room-temperature laser action at a wavelength of 1.55 ..mu..m in a new double heterostructure in which the active layer of Ga/sub x/Al/sub y/In/sub 1-x/-yAs is confined between two cladding layers of Al/sub u/In/sub 1-u/As. The structure was grown on InP by molecular beam epitaxy, and was pumped optically by a Q-switched yttrium aluminum garnet laser. Peak output power of up to 5 W was obtained at an incident power corresponding to four times that required for threshold without catastrophic degradation. Temperature dependence of the threshold power can be characterized by P/sub th/approx.exp(T/T/sub 0/) with T/sub 0/ = 60 /sup 0/C for 20 /sup 0/C< or =T< or =100 /sup 0/C.
