Eye-safe actively Q-switched microchip laser with an electro-absorbing semiconductor modulator

Abstract [en]

We present what we believe to be the first actively Q-switched monolithic microchip laser with a wavelength of 1.55 mum that uses an electro-absorbing semiconductor modulator. At an absorbed pump power of 130 mW and a switching voltage of 2.2 V, the laser produces 470-nJ pulses at a repetition rate of 10 kHz. The output is a stable single longitudinal mode with a center wavelength of 1.553 mu tm, and the transverse beam profile is close to an ideal Gaussian, with an M-2 value of 1.15.
