Ultrafast Science, Vol 2022 (2022)
As ultrafast laser technology advances towards ever higher peak and average powers, generating sub-50 fs pulses from laser architectures that exhibit best power-scaling capabilities remains a major challenge. Here, we present a very compact and highl

We have studied a three-level {\Lambda}-type atomic system with all the energy levels exhibiting decay. The system is described by a pseudo-Hermitian Hamiltonian and subject to certain conditions, the Hamiltonian shows parity-time (PT) symmetry. The

We demonstrate sub-20 fs single-stage post-compression of an Ytterbium-doped fiber laser. Dispersion-engineered dielectric cavity mirrors are used to control spectral broadening in a gas-filled multi-pass cell supporting a throughput of 98%.

We report on 100-W 132 MHz Yb:fiber amplifier seeded by a low noise oscillator. We tune the laser spectrum to match it to different applications while keeping noise properties and power performance of the system.

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.

Conference on Lasers and Electro-Optics.
We introduce the combination of multi-pass cell and multi-plate spectral broadening. We demonstrate the compression of 110-μJ pulses from 900-fs to 60-fs in a single stage and report broadening to 38-fs transform-limit by nonlinear mode-matching.
