Disk laser offers excellent scalability over a broad variety of average powers and pulse energies simply by changing the disk size and/or the number of disks in an amplifier. This makes the disk laser a leading candidate for applications ranging from

We have previously shown that the ceramic Yb:YAG-based edge-pumped disk laser amplifier offers significant advantages over traditional face-pumped disk amplifiers. Such amplifiers may be used in laser drivers for inertial confinement fusion, laser ac

We report on initial lasing of Tm:Lu2O3 ceramic laser with tunable output in the vicinity of 2 μm. Tm:Lu2O3 ceramic gain materials offer a much lower saturation fluence than the traditionally used Tm:YLF and Tm:YAG materials. The gain element is pum

We report on testing of an edge-pumped ceramic Yb:YAG disk laser having a tailored spatial gain profile for preferential amplification of the TEM00 mode. The disk has a composite construction with a Yb-doped large-aperture central portion cosintered

Tm:Lu2O3 has a multi–featured absorption spectrum in the usual pump band around 796 nm with peaks and valleys narrower than the bandwidth of conventional pump diodes in this range. As a result, accurate prediction of the spatial deposition of absor
