Power scalable TEM/sub 00/ CW Nd:YAG laser with thermal lens compensation

“…Finally, coplanar pumping and heat removal permit increasing the power of the laser simply by increasing the height of the pumped region. The zigzag optical path and side-pumped, side-cooled slab is the basis of many high-power solid-state laser designs [3], [8]- [10].…”

One hundred and twenty one W green laser generation from a diode-side-pumped Nd:YAG laser by use of a dual-V-shaped configuration

“…The generation of high-power green laser is particularly important for these applications [2][3][4][5][6]. Second harmonic generation (SHG) of Nd 3+ -doped solid-state lasers with the advantages of high efficiency, compactness, and robustness becomes the most effective way of generating highaverage-power green coherent radiation [1][2][3][4][5][6]. KTiOPO 4 (KTP) crystal and LiB 3 O 5 (LBO) crystal are often chosen as the SHG nonlinear crystal.…”

Laterally periodic resonator for large-area gain lasers

“…To extract available power from large-area gain, unstable resonators with graded reflective mirrors have been successful [1] but are not suitable for low-and medium-gain lasers. Another approach is use of the master oscillator power amplifier (MOPA) [2,3], which has a low-power but high-beam-quality laser as a master oscillator and large-area gain media as amplification stages. Hence MOPA combines the advantages of high beam quality with MO and the high energy storage of amplifiers.…”
