High efficiency passively mode-locked Nd:YVO 4 laser with direct in-band pumping at 914 nm.

A passively mode-locked Nd:YVO4 laser with the highest to date slope efficiency of 77.1% was demonstrated with in-band pumping at 914 nm. The laser produced 6.7 W of output power with 17 ps long pulses.

Multiwatt continuous wave Nd:KGW laser with hot-band diode pumping

We have demonstrated what we believe is the first continuous wave Nd:KGW laser with hot band diode pumping at ~910 nm. The laser produced 2.9 W of average output power in a diffraction limited beam.

Diode-pumped Nd:YVO 4 laser with discrete multi-wavelength tunability and high efficiency

Selectable and discretely tunable multi-wavelength diode-pumped Nd:YVO4 laser operating at 1064.0, 1073.1, and 1085.2 nm was demonstrated using a single intracavity birefringent plate. Under 11.2 W of absorbed pump power, the maximum output power of more than 3.8 W for any of the three wavelengths was achieved with slope and optical-to-optical efficiencies of more than 45% and 35%, respectively.

Passive mode locking of a Nd:KGW laser with hot-band diode pumping

We demonstrate passive mode locking of a Nd:KGd(WO4)2 laser diode-pumped at 910 nm. Semiconductor saturable absorber mirror was used to generate 2.4 ps pulses at a repetition rate of 83.8 MHz. An output power of 87 mW was obtained at 1067 nm.

Passively mode-locked Nd:YVO4 laser operating at 1073 nm and 1085 nm

A passively mode-locked Nd:YVO4 laser operating at 1073 nm and 1085 nm was demonstrated with an intracavity birefringent filter as the wavelength selecting element. The average output powers achieved were 2.17 W and 2.18 W with optical-to-optical efficiency of 19.6% and 19.7%, respectively. The slope efficiencies were more than 31% at both output wavelengths. The pulse durations at the highest average output power were 10.3 ps and 8.4 ps, respectively. We believe that this is the first report of mode locking of a Nd:YVO4 laser operating at 1073 nm or 1085 nm lines.

Dual-Wavelength CW Operations at 1064.1 & 1073.1 nm and 1064.1 & 1085.3 nm of Nd:YVO4 Laser
