A fiber-based approach that generates mid-infrared femtosecond pulses in the 3–4 (Formula presented.) m spectral region with microjoule-level single pulse energy is demonstrated. This is realized in a piece of gas-filled antiresonant hollow-core fi

We demonstrate band-edge-induced strong radiation at 3.5 µm wavelength from a gas-filled antiresonant hollow-core fiber that is pumped by femtosecond pulses at 2 µm. The high conversion efficiency allows the generation of sub-µJ level mid-infrared

We present an antiresonant hollow-core fiber-based bandpass optical filter. The device is realized by tapering down a section of tubular hollow-core fiber to a ratio of less than 0.5. Sweeping of the tube wall thickness-induced resonant bands in the

We report on the universality of the emergence of Akhmediev breathers in soliton effect pulse compression dynamics by using explicit analytic solutions of breathers and solitons in the non-linear Schrödinger equation. We show that at maximum compres

We report the generation of phase-matched long-wavelength radiation at a transmission band-edge of an anti-resonant hollow-core fiber filled with gas. This is achieved with the aid of the resonance-induced dispersion change at the band edge.

We generate the five phase-locked harmonics having an exact integer frequency ratio 1ω, 2ω, 3ω, — with a controlled carrier-envelope-phase. We also demonstrate the continuous generation of ultrafast optical amplitude waveforms with a repetition

Third International Conference on Applications of Optics and Photonics.
We have successfully generated a new broadband coherent light source in the continuous wave (CW) regime which is an ensemble of multi-harmonic radiations (2403, 1201, 801, 600 and 480 nm) by implementing a frequency dividing technology. The system is

We report on the synthesis of an ultrashort pulse train with a repetition rate of 125 THz by tailoring the phases and amplitudes of five phase-locked harmonics with an extremely-wide frequency spacing.

We report a dual-frequency injection-locked continuous-wave near-infrared laser. The entire system consists of a Ti:sapphire ring laser as a power oscillator, two independent diode-lasers employed as seed lasers, and a master cavity providing a frequ
