Abstract

Compression of diode laser pulses and broad spectral tuning of the compressed pulses is of current interest due to the expected increase in second harmonic and optical parametric oscillation efficiencies that could be realised due to the decreased pulse durations and narrow spectral bandwidths. With this objective in mind, we used commercial InGaAs/GaAS single-mode ridge waveguide lasers, which had an active stripe width of 3 μm and an emission wavelength of 980 nm. The typical gain-switched pulse duration was ~32 ps at a user-defined pulse repetition frequency, in the range 1 80-2 70 GHz and average powers up to 100 mW [1].
