Simultaneous Amplitude-Modulation and Harmonic Frequency-Modulation Mode Locking of Nd:YAG Laser

Abstract

Into a fundamentally AM modelocked Nd:YAG laser, we incorporate an electro-optic phase modulator driven at the 22nd harmonic (1.76 GHz). With only 0.6 Watts of RF power we obtain 17 ps pulses at 80 MHz and 8.0 Watts average optical power.
