Characterization of High-Harmonic Emission from ZnO up to 11 eV Pumped with a Cr:ZnS High-Repetition-Rate Source

We report the measurement of high-order harmonics from a ZnO crystal with photon energies up to 11 eV generated by a high-repetition-rate femtosecond Cr:ZnS laser operating in the mid-infrared at 2–3 μm, delivering few-cycle pulses with multi-watt average power and multi-megawatt peak power. High-focus intensity is achieved in a single pass through the crystal without a buildup cavity or nanostructued pattern for field enhancement. We measure in excess of 108 high-harmonic photons/second.

Octave-Spanning Cr:ZnS Femtosecond Laser with Intrinsic Nonlinear Interferometry

Octave-Spanning Cr:ZnS Femtosecond Laser with Intrinsic Nonlinear Interferometry

We report a few-cycle, super-octave, polycrystalline Cr:ZnS laser system with 4 W power at 78 MHz repetition rate, where all of the necessary optical signals for the measurement of the carrier–envelope offset frequency are generated intrinsically.

Super-Octave Longwave Mid-Infrared Coherent Transients Produced By Optical Rectification of Few-Cycle 2.5-μm Pulses

Super-Octave Longwave Mid-Infrared Coherent Transients Produced By Optical Rectification of Few-Cycle 2.5-μm Pulses

Femtosecond laser sources and optical frequency combs in the molecular fingerprint region of the electromagnetic spectrum are crucial for a plethora of applications in natural and life sciences. Here we introduce Cr:ZnS lasers as a convenient means for producing super-octave mid-IR electromagnetic transients via optical rectification (or intra-pulse difference frequency generation, IDFG). The results highlight the potential of this architecture for ultrafast spectroscopy and generation of broadband frequency combs in the longwave infrared.

Frontiers of Mid-IR Lasers Based on Transition Metal Doped Chalcogenides

TM ion doped II-VI semiconductors have been extensively studied since the 1960s by many research groups. However, the lasing of a Cr:ZnSe crystal was first reported in 1996 by scientists from Lawrence Livermore National Laboratory. In this publication, the authors formulated the major features that make these materials so attractive for middle infrared (MIR) laser applications.
