Performance Simulation of Side-Pumped Slanted Faces of High Power Yb:YAGYAG Thin-Disk Laser

Investigation of absorption pump light distribution in edged-pumped high power Yb:YAGYAG disk laser

In this article, we present a specific shape of disk laser which is side-pumped by four non-symmetric hollow- ducts. The use of non-symmetric hollow duct based on two goals of the uniformity of the pump light distribution profile and the homogeneity of pump light profile through the disk. First of all we simulated the pump light distribution in the disk by using Monte-Carlo ray tracing method. ...

High power Bessel-like laser beam by thin disk geometry

Diffraction-free beam and optical invariant field are special cases of optical wave propagation that have caught general attention in the last decade. Temporal solitons were the first class of optical signals to be recognized as being invariant under propagation (Hasegawa and Tapert, 1973) and to be experimentally demonstrated (Mollenaure et al., 1980). But, they require a nonlinearity to prese...

Side-pumped crystalline Raman laser.

A crystalline Raman laser is pumped at 90° to the Raman laser axis by a single pass from a line-focused 532 nm pump laser of pulse duration 10 ns. The Raman laser threshold was 6.1 mJ, and at 12 mJ pump energy, a maximum output energy of 2.7 mJ was obtained with a slope efficiency of 46%. The threshold pump intensity is within a factor of 2 of the same device when end-pumped. The results highli...

Femtosecond thin-disk laser with 141 W of average power.

We present a semiconductor saturable absorber mirror mode-locked thin disk laser based on Yb:Lu(2)O(3) with an average power of 141 W and an optical-to-optical efficiency of more than 40%. The ideal soliton pulses have an FWHM duration of 738 fs, an energy of 2.4 microJ, and a corresponding peak power of 2.8 MW. The repetition rate was 60 MHz and the beam was close to the diffraction limit with...

Characterization and optimization of mode-locking of a high-power Yb:YAG thin-disk laser

High-power and high-efficiency frequency-doubled fundamental-mode thin-disk laser

A highly efficient grating mirror for intra-cavity wavelength and polarization stabilization in a frequency-doubled Yb:YAG thin-disk laser enables up to 403 W of output power at an unprecedented efficiency of 40.7% in close-to fundamental-mode operation. OCIS codes: 140.3515, 190.2620.
