“…The reach of laser output wavelength could be significantly extended towards longer wavelengths by enabling the operation of the second or higher order Raman shift. 27 Numerical simulation results are in good agreement with experimental observations, providing important insight into output Raman pulse evolution. Output Raman pulses can be compressed to femtosecond pulses by applying linear dispersion.…”

We report a Raman fiber laser based on a multimaterial chalcogenide microwire. The microwire structure comprises a core of As 38 Se 62 , a cladding of As 38 S 62 , and a coating of poly-methyl methacrylate. The microwire is a robust, high confinement waveguide compatible with the mid-infrared. With the microwire inserted in a ring cavity, Raman laser oscillation at a wavelength of 2.025 lm occurs from synchronous pumping at a wavelength of 1.938 lm. The input peak power required to reach threshold is 4.6 W and the power slope efficiency is 4.5%. Numerical simulations are in good agreement with experimental results and predict chirp-free femtosecond pulses.

“…Thus, in comparison with Brillouin scattering or FWM, phase matching is automatically satisfied; this makes Raman lasing in WGRs relatively easy to implement. The ultrahigh optical Q in WGRs guarantees a very low Raman lasing threshold and even cascaded processes can be achieved, as has been demonstrated in silica microspheres [6,7], microtoroids [8,9], chalcogenide microspheres [10,11], and PDMS (polymer) WGRs [12]. Raman lasing in WGRs can be very useful for sensing applications since (i) it does not require a dopant in the resonator's material and (ii) it decreases the effective linewidth of the WGM through Raman gain.…”

We report on the fabrication of an ultrahigh quality factor, bottle-like microresonator from a microcapillary, and the realization of Raman lasing therein at pump wavelengths of $1.55~\mathrm{\mu m}$ and $780~\mathrm{nm}$. The dependence of the Raman laser threshold on mode volume is investigated. The mode volume of the fundamental bottle mode is calculated and compared with that of a microsphere. Third-order cascaded Raman lasing was observed when pumped at $780~\mathrm{nm}$. In principle, Raman lasing in a hollow bottle-like microresonator can be used in sensing applications. As an example, we briefly discuss the possibility of a high dynamic range, high resolution aerostatic pressure sensor

“…Low-threshold CW Raman lasing has been demonstrated in different silica WGM resonators, including microspheres [6], microtoroids [7], microbubbles, and microbottles [8,9]. CW WGM Raman lasing has also been reported in other materials such as coated polymers [10], chalcogenides [11,12], lithium niobate [13], and calcium fluoride [14][15][16][17]. In recent years, nanoparticle sensor applications based on such lasers have been reported [18,19], and anti-Stokes Raman lasing has been observed [20].…”

We investigate the mechanisms leading to phase locking in Raman optical frequency combs generated with ultrahigh Q crystalline whispering gallery mode disk resonators. We show that several regimes can be triggered depending on the pumping conditions, such as single-frequency Raman lasing, multimode operation involving more than one family of cavity eigenmodes, and Kerr-assisted Raman frequency comb generation. The phase locking and coherence of the combs are experimentally monitored through the measurement of beat signal spectra. These phase-locked combs, which feature high coherence and wide spectral spans, are obtained with pump powers in the range of a few tens of mW. In particular, Raman frequency combs with multiple free-spectral range spacings are reported, and the measured beat signal in the microwave domain features a 3 dB linewidth smaller than 50 Hz, thereby indicating phase locking.
