Advances in mid-infrared spectroscopy enabled by supercontinuum laser sources

Ivan Zorin et al.

Summary: Supercontinuum sources are fiber-based pulsed laser systems that generate high power spectral densities across a wide spectral range. This review discusses the current state and perspectives of supercontinuum technology in mid-infrared (mid-IR) spectroscopy. The article first explains the basic principles of supercontinuum sources and provides experimental analysis of their emission properties, such as power spectral densities, brightness levels, spectral stability, and beam quality. The authors identify the competitive advantages of supercontinuum sources over thermal sources or quantum cascade lasers in mid-IR spectroscopy. The unique features of supercontinuum radiation offer opportunities for improving established techniques and developing new analytical methods and instruments. The review concludes with a summary of recent advances and applications of supercontinuum sources in various mid-IR spectroscopy scenarios.

All-Fiber Mid-Infrared Supercontinuum Generation Pumped by Ultra-Low Repetition Rate Noise-Like Pulse Mode-Locked Fiber Laser

Xing Luo et al.

Summary: This study demonstrates the generation of broadband mid-infrared supercontinuum at room temperature using an ultralow repetition rate noise-like pulse mode-locked fiber laser. By inserting a standard single mode fiber and a dispersion compensation fiber into the long laser cavity of a Tm-doped fiber laser, mode-locked noise-like pulses with a repetition rate of approximately 190 kHz are obtained. The amplified noise-like pulse is then used to pump a highly nonlinear indium fluoride fiber, resulting in a flat mid-infrared supercontinuum with a coverage range from approximately 1500 nm to 4100 nm. The all-fiber mid-infrared supercontinuum laser source has a simple architecture and low cost. The study highlights the advantages of ultra-low repetition rate noise-like pulses in mid-infrared supercontinuum generation.

Algorithm for Solving a System of Coupled Nonlinear Schrodinger Equations by the Split-Step Method to Describe the Evolution of a High-Power Femtosecond Optical Pulse in an Optical Polarization Maintaining Fiber

Anton Bourdine et al.

Summary: This article proposes an advanced algorithm for numerically solving a coupled nonlinear Schrodinger equations system, which describes the evolution of a high-power femtosecond optical pulse in an optical fiber. The algorithm utilizes a variant of the split-step method and the Madelung transform to calculate the complex amplitude, eliminating the need to numerically solve differential equations directly for the phase component. This results in a significant reduction in computation time.

Supercontinuum generation of 314.7 W ranging from 390 to 2400 nm by tapered photonic crystal fiber

Haoyu Zhang et al.

Summary: By pumping a long-tapered photonic crystal fiber with a high-power laser source, a supercontinuum covering all visible wavelengths with an output power exceeding 300 watts was successfully achieved, with spectral flatness within 16 dB. This result indicates a threefold increase in the output power of the supercontinuum covering the visible range.

Supercontinuum generation in single-crystal YAG fibers pumped around the zero-dispersion wavelength

Michael Tripepi et al.

Summary: Yttrium aluminum garnet (YAG) is a potential supercontinuum medium for developing optical technologies in the short-wave infrared and mid-infrared wavelength range. Experimental results show that supercontinuum generation in undoped YAG fibers can cover a spectral region from 0.2 to 1.6 times the pump wavelength. Z-scan measurements also reveal little dispersion of the nonlinear index of refraction in YAG.

Ultra-broadband supercontinuum covering a spectrum from visible to mid-infrared generated by high-power and ultrashort noise-like pulses

Kuan-Yuan Chang et al.

Summary: In this study, single-mode fibers with different cutoff wavelengths were used as shortpass filters in a fiber-based supercontinuum generation system, along with an ytterbium-doped fiber amplifier to amplify pulses and achieve ultrashort high-power laser pulses of common wavelengths. The generated pulses were further launched into a photonic crystal fiber to produce one of the widest spectra in broadband supercontinuum generation, covering a broad spectral range from visible light to mid-infrared light.
