“…In the literature, several techniques exist to convert OFCs to higher wavelengths, such as difference frequency generation in periodically poled lithium niobate crystals − or supercontinuum generation. − In this work, we propose to convert frequency combs from the standard telecommunication band (∼1.55 μm) to the near-infrared around 2 μm by means of degenerate FWM occurring in a dispersion-controlled HNLF.…”

In this paper, we introduce an all-fiber dual-comb spectrometer based on an original design of a highly nonlinear fiber to efficiently convert frequency combs in the near-infrared from 1.55 μm to around 2 μm. We show that our spectrometer can be used to measure the absorption profiles of rovibrational transitions of CO 2 and N 2 O molecules, especially their collisional selfbroadening coefficients. The results show very good agreement with the HITRAN database, and thus, further measurements have been performed on a mixture of CO 2 /N 2 O to measure the broadening of the CO 2 absorption lines resulting from the presence of N 2 O.

“…However, the corresponding idler power with beam quality factor M 2 < 1.5, shown in Figure 3b, exhibited the opposite trend. The idler power of the wavelength beyond 4000 nm plummeted because material absorption became significant [21,31]. Over the whole tuning range, SRO could provide >200 mW of signal power with up to 4.2 W at a wavelength of 1726 nm, and >300 mW of idler power with up to 5.4 W at a wavelength of 2534 nm.…”

High-power and widely tunable continuous-wave optical parametric oscillators (cw OPOs), as mature radiation sources in the mid-infrared range, are limited by their frequency fluctuation. We built a cw OPO working at the near- and mid-infrared ranges and discuss the extent to which its frequency stability is affected by the mechanical temperature and the air pressure of the cavity. In addition, we artificially provoked mode hops by changing the above two factors to analyze the thermal-induced refractive index variation of the crystal. An inequality between the spacing of the hops and the free spectrum range (FSR) was observed. The wavelength stability of the cw OPO was guaranteed passively, and the longest mode-hopping-free time exceeded 13 h through sealing the cavity and thermal control. Further analysis of factors affecting frequency drift is critically essential for the reliability of cw OPO, particularly in environments outside the laboratory, and may provide a new method for high-precision tuning wavelengths.

“…Several types of wavelength-swept lasers, such as external-cavity semiconductor lasers (ECSLs), dye lasers, distributed Bragg reflector lasers, tunable solid-state lasers, verticalcavity surface-emitting lasers, distributed feedback lasers, and optical non-linear frequency conversion-based lasers have been developed in the last 50 years [13][14][15][16][17][18][19][20][21]. Compared to other types of wavelength-swept laser, ECSL has the prestigious characteristics of a large tuning range, high signal-to-source spontaneous emission ratio, narrow linewidth, and low cost, which is one of the most versatile measuring tools [22][23][24].…”

A high side-mode suppression ratio external-cavity wavelength-swept laser system with a wide mode-hopping free tuning range is developed. The proposed wavelength-swept laser is based on a single-angled facet gain chip in a classical Littman-Metcalf external-cavity configuration using a blazed diffraction grating as the feedback element. The output power, side-mode suppression ratio, and tunable range of the external-cavity wavelength-swept laser system are experimentally measured. Wide mode-hopping-free continuous wavelength tuning range about 100 nm in CL-band with a side-mode suppression ratio of more than 65.64 dB are realized. An output optical power of more than 14.12 dBm over the entire tunable region can also be achieved. The proposed external-cavity wavelength-swept laser system allows simultaneously high side-mode suppression ratio and no mode-hopping tunable radiation, thus opening a door for practical applications such as optical modulation schemes.
