Ultrashort cavity semiconductor lasers have been pumped at room temperature by AℓGaAs injection lasers. Peak powers of up to 10 mW were obtained in InP in the form of single longitudinal mode subnanosecond pulses. Conversion efficiency from the injection laser pump power to lasing power was up to 8 percent in InP. Tuning over 150 A° was seen.
