Continuous-wave and passively Q-switched Tm^3+-doped LuAG ceramic lasers

Passively Q-switched ceramic Nd3+:YAG/Cr4+:YAG lasers.

Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...

Continuous-wave and passively Q-switched cladding-pumped planar waveguide lasers.

Greater than 12 W of average output power has been generated from a diode-pumped Yb:YAG cladding-pumped planar waveguide laser. The laser radiation developed is linearly polarized and diffraction limited in the guiding dimension. A slope efficiency of 0.5 W/W with a peak optical-optical conversion efficiency of 0.31 W/W is achieved. In a related structure, greater than 8 W of Q -switched averag...

Passively Q-Switched Microchip Lasers Enable Ultrashort Pulses

high-peak-power subnanosecond pulses. No need for cumbersome high-voltage controllers or even a water cooling system. Passively Q-switched microchip technology for industrial lasers covers the range of hundreds of picoseconds down to 300 ps in the offerings of Teem Photonics. Peak powers in excess of 200 kW are readily available at 1 kHz using PowerChip microchip cavities, and a 50-kHz repetiti...

Passively synchronized Q-switched and mode-locked dual-band Tm3+:ZBLAN fiber lasers using a common graphene saturable absorber

Dual-band fiber lasers are emerging as a promising technology to penetrate new industrial and medical applications from their dual-band properties, in addition to providing compactness and environmental robustness from the waveguide structure. Here, we demonstrate the use of a common graphene saturable absorber and a single gain medium (Tm3+:ZBLAN fiber) to implement (1) a dual-band fiber ring ...
