200 fsec Optical Pulse Generation from a Hybrid Mode-locked Semiconductor Diode Laser-Amplifier System

Compact sources of ultrashort, high repetition rate, high peak power optical pulses are desirable for photonic switching, optical computing, optical clocking, and synchronization, nonlinear optical methods of volumetric optical data storage, and other areas of applied photonics networks. Monolithic hybrid modelocked semiconductor diode lasers provide ultrashort optical pulses at ultrahigh bit rates; however, the peak output power may not be sufficient for certain applications. In this report, a hybrid modelocked external cavity semiconductor laser system is described that produces pulses of 200 fsec in duration with 165 watts of peak power. These optical pulses represent both the shortest and most intense ever generated from an all semiconductor laser system.
