Abstract

We have developed a compact, all-solid-state self-mode-locked Cr4+:YAG laser. The laser is pumped by a cw laser-diode-pumped Nd:YVO4 laser and produces highly stable femtosecond pulses near 1.50 μm. Measurements of noise power spectra for frequencies below 10 kHz show that the diode-pumped laser system greatly improves the output energy fluctuation and pulse timing jitter compared with a laser system that uses a conventional arc-lamp-pumped cw Nd:YAG laser.

SH energy fluctuations of a self-mode-locked pulse train. The intensity is almost constant at a 0.6 V level (0.1 V/division). The inset is taken with a greater sensitivity of 5 mV/division. Both time scales are 10 ms/division.

Fig. 3

First-order power spectrum of the self-mode-locked pulse train for a low-resolution regime with a frequency span of 1 MHz and a resolution bandwidth (RBW) of 1 kHz. The darker curve represents the LD-pumped laser system, and the lighter curve represents the arc-lamp-pumped laser system. Both laser systems have the same pulse width (60 fs) and average output power (150 mW).
