6.5 W 1.3 mum passively Q-switched output was demonstrated from a side-pumped Nd doped Gd0.6Y0.4VO4 bounce laser in combination with V:YAG saturable absorber crystal. Slope efficiency of 24% was achieved.
A novel, all-fiber-integrated supercontinuum (SC) laser is demonstrated and provides up to 10.5 W time-averaged power with a continuous spectrum from ~0.8 to 4 mum. The SC is generated in a combination of standard single-mode fibers and ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) fluoride fibers pumped by a laser-diode-based cladding-pumped fiber amplifier system. The output SC pulse pattern can be modulated...
Hybrid Si/InGaAsP Fabry-Perot evanescent lasers are fabricated via wafer bonding. Compared with previous similar devices, the current threshold density, turn-on voltage, output power and slope efficiency are all improved. Images show modal confinement to Silicon.
Reliability and lifetime of quasi-CW laser diode arrays are greatly influenced by their thermal characteristics. This paper examines the thermal properties of laser diode arrays operating in long pulse duration regime.
This paper discusses the significant advancements in the 2-micron laser development. A world record one-Joule-per-pulse energy laser system and an advanced thermal management with fully conductive cooled laser technique are discussed.
High-efficiency high-power operation of 2 at.% crystalline Nd:YAG is demonstrated. CW output power of 46.1 W and slope efficiency of 60% are obtained, and 11 mJ pulses at 100 Hz with QCW-pumping are achieved with 12 ns Q-switched pulses.
Up to 700 kHz high repetition active Q-switching was achieved with a pulse-width of < 40 ns by using a diode-side-pumped Nd:GdxY1-xVO4 bounce amplifier. The average output power of 17.5 W was obtained at a pump power of 41 W.
