RESEARCH AND DEVELOPMENT OF DIODE-PUMPED PASSIVELY Q-SWITCHED Nd:YVO4 LASERS USING Cr4+:YAG CRYSTAL AS SATURABLE ABSORBER

The results in research and development of diode-pumped passively Q-switched Nd:YVO4 lasers are presented with Cr4+:YAG crystal used as an intra-cavity saturable absorber. Using a-cut Nd:YVO4 laser crystals, the passively Q-switched lasers have been successfully developed and provided stable single shortest pulses of 40 ns at the repetition rate of 18.5 kHz, the maximal average output power of 180 mW was achieved corresponding to the optical efficiency of 9% and the slope efficiency of 16%. The dependences of average output power, repetition rate, pulse width and peak power on pump diode power for different transmissions of output mirror are also investigated.

A fiber laser resonantly pumped Q-switched mode locked Er :YAG ceramic 1645 nm laser using graphene as the saturable absorber is realized. The mode-locked pulses with average output power of 320 mW, Q-switching envelope temporal width of 10 μs and mode-locking repetition rate of 83 MHz can readily be generated from the laser. To the best of our knowledge, this is the first report on the graphene-based Q-switching mode locked Er :YAG ceramic laser emitting around 1645 nm.

AbstractWe have demonstrated 4-μm InAs/InGaSb/AlSb interband cascade lasers with optical output power close to 0.5 W per facet with 1-μs pulses at 1 kHz repetition rate. At 10% duty cycle, an average output power ∼20 mW was realized. External and internal quantum efficiencies exceeding 200% have been achieved at 80 K.
