Generation of High-Power Ultrashort Optical Pulses Using a Semiconductor Laser with Controlled Current Pumping

Аннотация

Fiber-coupled semiconductor lasers are studied under pumping with high-power short current pulses. Appropriate parameters of the current pumping make it possible to substantially reduce the output pulse duration to 80 ps for a single-mode laser and 120 ps for a wide-stripe multimode laser at a pump pulse duration of 1 ns and to 40 ps for the single-mode laser at a pump pulse duration of 0.5 ns.
