Summary: For the first time, diode-pumped continuous-wave and passively Q-switched Nd:LuAG ceramic microchip lasers at 1064 nm and 1053 nm have been demonstrated. The continuous-wave operation achieved maximum output powers of 1.62 W and 0.75 W for the two lasers, respectively. Using a Cr:YAG crystal as a saturable absorber, the lasers can also operate in passively Q-switched regimes with sub-nanosecond pulse durations of 489 ps and 556 ps, respectively. The all solid-state microchip lasers show great potential for high performance laser generation with sub-nanosecond short pulse duration, high single pulse energy, and high pulse peak power.

Summary: We report the generation of the first sub-60 fs pulse from a diode-pumped SESAM mode-locked Yb-laser using a non-centrosymmetric Yb:YAl3(BO3)4 crystal. By utilizing a spatially single-mode, fiber-coupled 976 nm InGaAs laser diode, the laser exhibited a slope efficiency of 65.1% and a wavelength tuning range of 59 nm. With the implementation of a commercial SESAM and a 1 mm-thick laser crystal, the laser achieved pulses as short as 56 fs at a central wavelength of 1044.6 nm.

Summary: A high-performance diode-tandem-pumped actively Q-switched Tm:YAP laser is demonstrated, achieving a maximum output power of 10.6 W with a pulse width of 37 ns, a pulse energy of 2.12 mJ, and a peak power of 57.3 kW at a pulse repetition rate of 5 kHz. Comparatively, an actively Q-switched Tm:YAP laser with a single gain crystal double-end pumped obtains a maximum output power of 6.8 W with a pulse width of 45 ns, a pulse energy of 1.36 mJ, and a peak power of 28.3 kW at the same pulse repetition rate. The experimental results clearly reveal the effect of diode-tandem-pumping regime on lowering down the thermal load of gain medium.

Summary: In this study, single crystals of yttrium orthoaluminate (YAlO3) activated with Yb3+ ions and additional nonisovalent Li+ and Hf4+ impurities were grown and their spectral characteristics, including those exposed to gamma-ray irradiation, were measured. The results revealed the functional role of additional impurities and showed the efficiency of using these impurities to obtain crystals with low concentration of anion vacancies and associated color centers in YAlO3:Yb. The mechanisms of incorporation and charge compensation of Li+ and Hf4+ ions in YAlO3:Yb were also considered based on the results obtained.
