Continuous wave (CW) laser operation of the 5.0 at.% Yb:GdYAG ceramic laser has achieved 4.27 W output power with 26.7% slope efficiency. Passive mode-locking properties of the ceramic was also firstly demonstrated with a semiconductor saturable absorbing mirror (SESAM). Stable mode-locked ...
A diode-pumped passively mode-locked Yb:YAG ceramic laser was demonstrated. 417 and 286 fs pulses with average powers of 250 and 25 mW were obtained at 1030 nm using 1 and 0.1% output couplers, respectively. 233 fs pulses with an average power of 20 mW were also obtained at a center ...
YAG掺镱脉冲持续时间平均功率We experimentally demonstrated a diode-pumped Kerr-lens mode-locked femtosecond laser based on an Yb:YAG ceramic. Stable laser pulses with 97-fs duration, 2.8-nJ pulse energy, and 320-mW average power were obtained. The femtosecond oscillator operated at a central ...
摘要: 414W CW operation of a diode edge-pumped, composite all-ceramic Yb:YAG microchip (a 3mm-diameter core with a 200μm thickness) laser was successfully demonstrated. The emission power density of 0.29MW/cm3 from the core is highest ever reported....
DIODE-PUMPED SOLID-STATE LASERS: Yb:YAG ceramic laser produces modelocked pulses Doped ceramic is the gain material of the future for many forms of diode-pumped solid-state lasers: if fabricated correctly, a ceramic gain material can have the transparency and the performance of a crystalline gain...
A monolithic pumped laser cavity design is disclosed. Elements of the laser cavity, such as gain material, Q-switch, reflector, and outcoupler, are contact bonded together with a th
Now, researchers at Ibaraki University (Ibaraki, Japan) and RIKEN (Saitama, Japan) have demonstrated the first mode-locked ytterbium-doped yttrium aluminum garnet (Yb:YAG) ceramic laser, a device that has demonstrated the shortest pulses for diode-pumped ceramic lasers without Kerr lens modelockin...
