We present real-time waveform characterization of ultrashort pulses by the use of a pulse-front tilt in frequency-resolved optical gating capable of carrier-envelope phase determination. Simultaneous measurement of cross-correlation frequency-resolve

We have demonstrated the generation of supercontinuum (SC) pulses in bulk, using femtosecond pulses directly derived from a Tm:YAP regenerative amplifier. The SC spans from 380 nm−4 μ m. Such an SC combined with the applied 1937-nm pump pulse can

Sub-single-cycle pulses in the mid-infrared (MIR) region were generated through a laser-induced filament. The fundamental (ω1) and second harmonic (ω2) output of a 30-fs Ti:sapphire amplifier were focused into nitrogen gas and produce phase-stable

This paper is a perspective article which summarizes the development and application of sub-cycle mid-infrared (MIR) pulses generated through a laser filament. The generation scheme was published in Applied Sciences in 2013. The spectrum of the MIR p

Mid-infrared supercontinuum generation in polarization-maintained fluoride fibers has been demonstrated. The coherence of the supercontinuum is dramatically im-proved by reducing the round trip number of the 2 µm Tm:YAP regenerative amplifier.

We present mid-infrared (MIR) supercontinuum generation in polarization-maintained ZBLAN fibers pumped by 2 µm femtosecond pulses from a Tm:YAP regenerative amplifier. A stable supercontinuum that spreads from 380 nm to 4 µm was generated by coupli

Ultrafast laser systems operating around 1.7 μm to 1.8 μm are powerful tools to extend the penetration depth of mulitphoton microscopes [1,2]. However, radiation at this wavelength region is not readily available and thus frequency shifting was nec
Characterization of Supercontinuum Pulses Generated using a 2μm Thulium-Based Regenerative Amplifier

Pursuit of high energy mid-infrared optical parametric amplifiers (MIR-OPA), for use in high harmonic generation applications, led to the development of 2 μm lasers. In particular thulium based systems are of great interest for their capability of b
