“…Therefore, Er 3+ doped 1.5-μm lasers have been widely studied recently years [7][8][9][10][11][12][13][14][15]. Most applications of 1.5-μm lasers require high repetition rate Q-switched pulse modes.…”

We report, for the first time to our knowledge, an acousto-optic Q-switched Er,Yb:YAl3(BO3)4 crystal laser operating in the 1.5 -1.6 μm spectral region. The output characteristics of the lasers with different duty cycles, pulse repetition frequencies (PRF) and output couplers were investigated. The maximum single pulse energy of 91 μJ with the pulse width of 135 ns and the PRF of 5 kHz was achieved when the transmission of output coupler T = 1% and the duty cycle was optimized at 2.5%. The shortest pulse width of 90 ns was obtained at the PRF of 3 kHz for the transmission of output coupler T = 1.5%. The blue shift of laser emission and shortening of pulse width with reduction of PRF and increment of the pump power were observed.

Ultrafast laser physics continues to advance at a rapid pace, driven primarily by the development of more powerful and sophisticated diode-pumping sources, the development of new laser materials, and new laser and amplification approaches such as optical parametric chirped-pulse amplification. The rapid development of high average power cryogenic laser sources seems likely to play a crucial role in realizing the long-sought goal of powerful ultrafast sources that offer concomitant high peak and average powers. In this paper, we review the optical, thermal, thermo-optic and laser parameters important to cryogenic laser technology, recently achieved laser and laser materials progress, the progression of cryogenic laser technology, discuss the importance of cryogenic laser technology in ultrafast laser science, and what advances are likely to be achieved in the near-future.

“…~1.6 μm eye-safe wavelength regime lasers based on Er 3+ -doped gain media have many important applications in remote sensing, free space communications and as the pump source for generating 3-5 μm mid-infrared radiations via nonlinear frequency conversion. In recent years, high performance laser operations at this wavelength region are also demonstrated with ceramic structured Er: Sc2O3, Er:Y2O3 and Er:YAG gain materials [5][6][7][8][9][10]. Among these differential ceramic hosts, YAG is the most technologically advanced and popular one with spectral and thermo-mechanical robustness.…”

We report on high-power continuous-wave operations of an Er:YAG ceramic laser in-band pumped by a cladding-pumped Er,Yb fiber laser at 1532 nm. With an output coupler of 10% transmission, the ceramic laser yielded 16.7 W of continuous-wave output at 1645 nm for 28.8 W of incident pump power, corresponding to a slope efficiency of 61.0% with respect to the incident pump power. The lasing wavelength switched to 1617 nm when output couplers of > 20% transmission were used. Up to 16.2 W of 1617 nm output was generated for 33.0 W of incident pump power, corresponding to a slope efficiency of 51.8%. Graphene Q-switched operation of Er:YAG cermic laser at 1645 nm was also demonstrated with stable pulses of 30-74 kHz repetition rates and 1.5-6.4 μs pulse widths.
