Abstract

A diode-end-pumped Nd:LGGG dual-wavelength synchronously mode-locked laser operation at 1.06 μm was demonstrated. The maximum average output power of 475 mW was obtained. The two wavelengths were simultaneous mode-locked at 1060.9 and 1062.7 nm with the pulse duration of 6.3 ps. A laser frequency beat was observed on top of the autocorrelation trace in the operation, corresponding to the 0.48 THz signal of stationary wave interference pattern.
