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: This study demonstrates the generation of a 1645-nm single-frequency vortex beam with narrow linewidth from an Er:YAG nonplanar ring oscillator (NPRO) using an annular pump beam. The pump beam, shaped by an axicon, is derived from a 1532-nm fiber laser. Under a pump power of 13 W, the Er:YAG NPRO generates a 1.96-W single-frequency vortex beam. The linewidth of the 1645-nm vortex laser is measured to be 6 kHz. This work presents a convenient approach for the generation of single-frequency vortex beams.

Summary: The performance of a Fe:ZnSe laser was investigated under different excitation schemes using a pulsed diode side-pumped Er:YAG laser. At liquid nitrogen temperature, the Fe:ZnSe laser achieved a pulse energy of 53 mJ with a slope efficiency of 42% relative to absorbed pump energy when pumped by a free running 360-μs Er:YAG laser. At room temperature, two optical schemes were considered, one utilizing independent cavities for the Fe:ZnSe and Er:YAG lasers, and the other coupling the cavities of both lasers and using the Fe:ZnSe crystal as both an active element for the Fe:ZnSe laser and a passive shutter for the Er:YAG laser. The Fe:ZnSe laser produced pulses with less than 200 ns duration and approximately 1 mJ energy at a repetition rate of up to 50 kHz, and the experimental waveforms of the laser pulses were approximated by rate equations.
