Abstract:
We demonstrate the diode laser-based generation of mode-locked pulses with 290 fs temporal width and 69 W peak power at a centre wavelength of 1067 nm. The laser diode is operated in an external cavity configuration at a repetition rate of 1.05 GHz. The laser operates passively modelocked with a reverse biased absorber section. The chirped output pulses are compressed close to the transform limit by means of an optimized grating compressor. This tailored pulse compression delivers almost transform limited pulses with specifications sufficient for THz time domain spectroscopy or nonlinear microscopy applications.
