Abstract

We have demonstrated a diode-laser-pumped, cw, mode-locked Nd:glass laser oscillator. With a 0.5% output coupler the pump threshold for mode-locked operation was 22.9 mW. The mode-locked pulse width was shorter than 36.5 psec, which was the response time of the fast photodiode and the sampling oscilloscope. Diode-laser-pumped mode-locked operation was also extended to Nd:YAG.

Experimental setup of a diode-laser-pumped and mode-locked Nd:glass laser. The laser can be simultaneously pumped by a diode laser and a dye laser focusing through the high-reflectivity (HR) turning mirror into the gain medium, which is at Brewster angle in a three-mirror cavity.

Fig. 2

(a) Second-harmonic-generation autocorrelation trace of a cw pumped and mode-locked Nd:glass laser, pumped by a combination of a cw diode laser and a cw Rhodamine 6G dye laser. The 27.4-mW diode laser provided 66.8% of the total pump power. Horizontal scale, 12.76 psec/division. Pulse FWHM is estimated to be 9.7 psec, corresponding to the trace FWHM of 13.7 psec assuming a Gaussian pulse shape. (b) Mode-locked output of a 20-mW cw diode-laser-pumped Nd:YAG laser as detected by an InGaAs photodiode and displayed on a sampling scope. Pulse FWHM 105 psec.
