“…Figure 1 shows the schematic of our experimental setup. Two pump beams with spectra centered at 786 nm and 837 nm are generated from the dual-wavelength Ti:sapphire laser system [15]. The frequency difference between the two pump beams is chosen as 23.25 THz to resonate with the vibrational Raman frequency of sulfur hexafluoride (SF 6 ).…”

It has been observed that when the multi-frequency Raman scattering process is pumped by two frequency chirped pulses in the transient regime, the anti-Stokes orders are spectrally broadened on the lower-frequency side, causing each of the orders to have a broader spectrum with double-peak pattern. In this article, we employ frequency-resolved optical gating to study the spectral shift of the first anti-Stokes Raman order. A double-pulse model is introduced to determine the electric field of the anti-Stokes orders from the experimental FROG spectrogram. With the help from the double-pulse model, we demonstrate that the double-peaked spectrum comes from linear Raman scattering between manifolds in the two-photon dressed states.

“…In short, it is a CPA based dual wavelength laser amplifier. The dual-wavelength oscillator is identical to that described by Dykaar [14] except that we use different mirror coatings in order to have the two wavelengths widely separated [5] . A dual wavelength pulse stretcher after that stretched the pulses to about 200 ps.…”

“…In the present, there are three ways to generate micro-joule level femtosecond mid-infrared laser pulses: the free electron laser [2] , which could generate pulse energies of 2 µJ at a wavelength of 5 µm with a pulse duration of 350 fs; a combination of optical parametric amplification and difference frequency generation (DFG) [3,4] , which produces 4.5 µJ sub-ps mid-infrared pulses; and a direct DFG scheme based on a high intensity, dual-wavelength laser system [5] . This one-step DFG produced 1.5 µJ 600 fs pulses at 10 µm, via mixing the output of the dualwavelength regenerative amplifier [6] , 7.4 µJ 500 fs at 10 µm based on a dual-wavelength multipass laser amplifier [7] .…”

Intense mid-infrared was generated by direct frequency mixing two pulses from a dual-wavelength Ti:sapphire system. From a multipass amplifier we generated two tunable wavelength femtosecond pulses with a total energy of 15 mJ. Pulse energy of 1.6 µJ and 7.4 µJ of mid-infrared light is achieved with and without its multipass amplifier at 9-11 µm, with pulse duration of 500 fs.infrared and far-infrared lasers, ultrafast lasers, laser amplifiers

“…The seed laser mainly determines the central wavelength of the system and its ultimate spectrum width. By engineering the laser cavities, wavelength-tunable and dual-wavelength lasers have been used in CPA systems to enable wavelength-tuning and dual-wavelength operation in Ti: Sapphire laser systems [10,11]. Broadband seed lasers have undergone dramatic development [12,13], although their amplification is restricted by the gain-narrowing effect.…”

Chirped pulse amplification (CPA) has been a commonly used methodology to obtain powerful ultrashort laser pulses ever since its first demonstration. However, wavelength-tunable CPA systems are much less common. Wavelength-tunable ultrashort and intense laser pulses are desirable in various fields such as nonlinear spectroscopy and optical parametric amplification. In this work, we report a 1720 nm–1800 nm tunable CPA system based on Tm-doped fiber. The tunable CPA system contains a seed laser, a pulse stretcher, two cascaded amplifiers and a pulse compressor. The dispersion-managed seed laser cavity emits wavelength-tunable laser pulses with pulse durations of several ps and spectral widths from 25 nm to 34 nm. After being stretched temporally to tens of ps, the laser pulses are then amplified in two-stage amplifiers and compressed in a Treacy-type compressor. At 1720 nm, the maximum average power of 126 mW is obtained with a pulse duration of 507 fs; at 1800 nm, the maximum average power of 264 mW is obtained with a pulse duration of 294 fs. The pulse repetition rates are around 22.7 MHz. We perform an analysis of the system design based on numerical simulations and go on to suggest further steps for improvement. To the best of our knowledge, this is the first demonstration of a tunable CPA system beyond 1.1 μm. Considering the specific wavelength range, this wavelength-tunable CPA system is highly desirable for biomedical imaging, sensing, and parametric amplifiers.
