چکیده
We present the nonlinear self-compression of pulses from a high repetition rate thuliumdoped fiber laser system using a gas-filled antiresonant hollow-core fiber. Sub-3-cycle pulses with several GW peak power at 21.4 W of average power have been generated. OCIS codes: (140.3070) IR and far-IR lasers; (320.5520) Pulse compression; (340.7480) X-rays, soft x-rays, (EUV)

Nonlinear pulse compression to 43 W GW-class few-cycle pulses at 2 μm wavelength.
High-average power laser sources delivering intense few-cycle pulses in wavelength regions beyond the near infrared are promising tools for driving the next generation of high-flux strong-field experiments. In this work, we report on nonlinear pulse compression to 34.4 μJ-, 2.1-cycle pulses with 1.4 GW peak power at a central wavelength of 1.82 μm and an average power of 43 W. This performance ...
متن کاملGeneration of micro-J pulses in the deep UV at MHz repetition rates
Although ultraviolet (UV) light is important in many areas of science and technology, there are very few if any lasers capable of delivering wavelength-tunable ultrashort UV pulses at MHz repetition rates. Here we report the generation of deep-UV laser pulses at MHz repetition rates and μJ-energies by means of dispersive wave (DW) emission from self-compressed solitons in gas-filled single-ring...

متن کاملHigh harmonic generation with long-wavelength few-cycle laser pulses
We report the extension of hollow-core fibre pulse compression to longer wavelengths. High-energy multi-cycle infrared pulses are generated via optical parametric amplification and subsequently broadened in the fibre. 2.5-cycle pulses at the Signal wavelength (1.4 μm) and 1.6-cycle pulses at the Idler wavelength (1.8 μm) in the sub-millijoule regime have been generated. New compression schemes ...
متن کاملCEP stable 1.6 cycle laser pulses at 1.8 μm.
By using the novel approach for pulse compression that combines spectral broadening in hollow-core fiber (HCF) with linear propagation in fused silica (FS), we generate 1.6 cycle 0.24 mJ laser pulses at 1.8 μm wavelength with a repetition rate of 1 kHz. These pulses are obtained with a white light seeded optical parametric amplifier (OPA) and shown to be passively carrier envelope phase (CEP) s...
