چکیده
We report operation of a laser-diode side-pumped Nd: YAG laser with a novel pumping geometry that ensures efficient conversion of pump energy into the TEM(00) mode. Of the 1064-nm output, 11.8 mJ of energy was obtained in a 200-micros pulse with 64 mJ of pump energy at 808 nm. The overall conversion and slope efficiencies were 18% and 23%, respectively.

We describe the laser performance and thermal properties of side-pumped Nd:YAG rod lasers that use ibercoupled diode lasers as pump sources. Utilizing a nearly homogeneous pump light profile, we realize an output power of more than 60 W in TEM(00) mode operation with optical-to-optical efficiencies of more than 25%. In multimode operation, optical slope efficiencies of more than 46% are observed.

We have built a diode-laser-pumped Nd:YAG slab laser that emits 40 W of cw power in a TEM(00) mode and 72 W of power in multimode operation when pumped with 235 W. The slope efficiencies are 22% for TEM(00)-mode operation and 36% for multimode operation. The laser uses a zigzag slab geometry to reduce thermally induced distortions and operates at less than one wave of distortion at the full pum...

We have demonstrated a diode-laser-pumped, cw, mode-locked Nd:glass laser oscillator. With a 0.5% output coupler the pump threshold for mode-locked operation was 22.9 mW. The mode-locked pulse width was shorter than 36.5 psec, which was the response time of the fast photodiode and the sampling oscilloscope. Diode-laser-pumped mode-locked operation was also extended to Nd:YAG.
