We introduce a new concept to frequency shift a high-power laser using a waveshaper and a multi pass cell. We demonstrate this concept by experimentally frequency shifting a 200 fs laser from 1030 nm to 1000 nm.

We developed a simulation of a beam tiled aperture combining system with n emitters. Using the Fourier propagation method, we calculate the far-field pattern depending on (n-1) relative phase parameters. We then simulate the phase noise as a time ser

We show deep reinforcement learning for phase stabilization in tiled aperture coherent beam combining. The trained agent was able to stabilize the phase using only a far-field image as input.

At the beginning of 2016, the first direct detection of a gravitational wave by a laser-based Michelson interferometer has been reported. So far, the number of confirmed detections has raised to three and will certainly increase further. Thereby, man

Coherent beam combining is a method to scale the peak and average power levels of laser systems beyond the limit of a single emitter system. This is achieved by stabilizing the relative optical phase of multiple lasers and combining them. We investig

We demonstrated an all-normal-dispersion nonlinear polarization rotation mode-locked Tm:ZBLAN fiber laser in the 2 μm wavelength band. All fibers in the experiment were ZBLAN fibers with normal dispersion in the wavelength band. An average power of
