“…[ 4 ] Coherent anti‐Stokes Raman spectroscopy (CARS) is an alternative nonlinear scheme for Raman gas analysis; broadband CARS based on employing a supercontinuum and resolving spectra on a spectrometer has realized simultaneous multispecies detection in a kagomé style [ 5 ] and a single ring hollow‐core photonic crystal fiber (SR‐PCF). [ 6 ] Other applications of gas‐filled PCF include mid‐IR laser and supercontinuum generation. Mid‐IR lasers generated by stimulated Raman scattering [ 7 ] and population inversion [ 8 ] in gas‐filled fiber have been reported.…”

We demonstrated high‐resolution continuous‐wave (CW) coherent anti‐Stokes Raman spectroscopy of gaseous samples in a single ring hollow‐core photonic crystal fiber. Pump beam and Stokes beam were provided by CW single longitudinal mode lasers. These narrow linewidth lasers brought the benefit of a spectral resolution of 99 MHz. The high resolution allowed a measurement of a linewidth 0.3 GHz of the ν1 transition of CO2 in a gas mixture with partial pressure of 0.15 MPa and total pressure of 0.9 MPa. Pump beam from a tunable dye laser and Stokes beam from an external cavity diode laser were coupled into the fiber containing gaseous CO2. Fundamental mode phase matching was achieved by tuning gas pressure. The long interaction length provided by the hollow fiber yielded a 60‐dB increase in the anti‐Stoke signal. The attained signal to noise ratio of the spectrum of ν1 component of 0.6‐MPa CO2 was ~25,000 with 152‐mW pump power and 1.4‐mW Stokes power.

“…The research results demonstrated that using the supercontinuum allowed for the simultaneous detection of multiple gases within the short integration time, achieving the LOD in the ppb range for specific gases. Tyumenev et al [83] reported the CARS in a gas-filled single-ring HC-PCF using a pump-probe configuration. Their study demonstrated that simultaneous multi-species CARS with an LOD of 20 ppm was possible.…”

In recent years, detecting and quantifying multiple gases have garnered widespread attention across various fields, particularly in volatile organic compound (VOC) detection, which holds significant importance for ecosystems and the medical field. The Raman spectroscopy has been widely used in multi-gas detection due to its advantages in fast response speed and non-destructive detection. This paper reviews the latest research progress of the multi-gas sensing technology in the Raman spectroscopy, focusing on using the hollow-core fiber to enhance the gas signal intensity. The basic principles of the fiber-enhanced Raman spectroscopy are introduced. The detailed discussion includes the system architecture, parameter configuration, and experimental results. Then, the latest advances in the coherent anti-Stokes Raman scattering multi-gas detection technology are reviewed. Finally, the challenges faced by the hollow-core fiber in practical applications are discussed.

“…Most of the spectral detection techniques can only detect a species at the same time, whereas Tyumenev et al achieved simultaneous multi-species CARS with a detection limit of 20 ppm using tapered PCF combined with single-ring ARF, where the long collinear path length offered by the ARF strongly enhanced the efficiency of the Raman interactions [122]. Alternatively, simultaneous detection of multiple Raman resonances can be realized by a multiplex CARS system.…”

With the development of laser technology, microstructured optical fibers (MOFs) have become an important part of ultrafast optics, providing excellent platforms for ultrafast laser pulse generation, amplification, and compression, promoting the development of fiber laser systems to generate high power, high pulse energy, and few-cycle duration pulses. MOFs extend the ultrafast laser spectrum to the vacuum ultraviolet (VUV) and even extreme ultraviolet (EUV) regions based on dispersive wave emission and high harmonic generation, as well as to the mid-infrared region based on soliton self-frequency shift (SSFS), contributing compact and low-cost light sources for precision microscopy and spectroscopy. In this paper, first several common types of MOFs are introduced, then the various applications of MOFs in ultrafast optics are discussed, mainly focusing on the aspects of ultrafast laser pulse scaling in pulse energy and spectral bandwidth, and finally the possible prospects of MOFs are given.
