Abstract

Low threshold cw laser emission from a semiconductor disk laser emitting at 1260 nm was demonstrated. Using high quality metal-organic vapor phase epitaxy (GaIn) (NAs) material, nonradiative processes could be minimized. As a consequence, threshold pump power densities have been reduced down to 5 kW/cm2. The capture efficiency of carriers into the quantum wells was found to be uncritical. [ABSTRACT FROM AUTHOR]

Abstract

The nanosecond dynamics of near-infrared semiconductor disk lasers is investigated experimentally and theoretically. Lasing and photoluminescence following barrier pumping are analyzed. Their spectral and temporal features such as luminescence overshoot and clamping, delay of lasing onset, and redshift of the emission are explained by a rate equation model taking into account the microscopic gain and luminescence.
