In this submission, we report a maximum 638-W fiberized chirped-pulse-amplification (CPA) laser system with a bulk reflection grating compressor. The system is able to emit 338-W compressed pulses of 624 fs centered at 1 µm, corresponding to a pulse

Femtosecond fiber lasers in the anomalous dispersion regime, such as Er and Tm lasers with wavelengths longer than 1.3 μm, rely on nonlinearity for spectral broadening and pulse compression. At high intensities, the nonlinearity becomes uncontrolled

High power femtosecond fiber laser systems typically rely on self-similar amplification, large scale chirped pulse amplification (CPA), or higher-order soliton pulse compression. In any of these system architectures the control or minimization of fib

We demonstrate both numerically and experimentally that self-phase modulation-enabled spectral selection generates wavelength tunable energetic pulses that are tightly synchronized to the excitation pulses. The synchronization quantified by relative

We demonstrate a 5 W, 65 fs single-mode Er fiber comb based on efficient pulse compression of gain-narrowed pulses from a chirped pulse amplification system. We generate two octaves of midinfrared with these pulses.

We compress a 5 W, 65 fs Er fiber frequency comb to 3 cycles and MW peak power. We show generation of 1 mW of two-octave wide midinfrared.

We present results of directly measured acetone absorption in the mid infrared using high-powered broadband dual comb spectroscopy. The technique developed is applicable to a wide variety of systems with mid infrared spectral features.

The midinfrared spectral region provides direct access to molecular vibrational transitions. The stronger coupling in the midinfrared creates possibilities for sensitive molecular detection [1] and control. As technology advances, midinfrared laser s

Femtosecond power scaling in anomalous dispersion waveguides like telecom fiber is limited by runaway pulse collapse. We achieve an order of magnitude increase over previous femtosecond erbium fiber lasers by using phase-only pulse shaping in a stret

We demonstrate a high-power offset-free ultrafast mid-infrared (IR) laser source based on difference-frequency generation (DFG). Powerful signal pulses are obtained by filtering
