“…Owing to their strong average and peak power scaling ability and wide range of wavelength coverage, solid-state lasers are critical for space exploration, defense, and manufacturing. [43][44][45] In particular, SLM solid-state lasers are ideal for applications where a high-coherence light source is required, including Doppler wind lidar, atmospheric composition measurement, gravitational wave detection, sodium guide star, and nonlinear optics. [46][47][48] In a standing wave cavity, the frequency distance between each longitudinal mode is described as follows:…”

With high-temporal coherence and low-phase noise, narrowlinewidth lasers have important applications in spectroscopy, holography, and coherent detection. At present, ultra-narrowlinewidth lasing is generated by solid-state, optical fiber, and semiconductor lasers, which serve as a good light source for scientific research and industrial applications. In this article, we summarize the fundamental techniques and review recent developments in narrow-linewidth lasers. Moreover, typical applications of narrow-linewidth lasers are discussed to provide reliable and easy-to-use references for comparing the performance of narrow-linewidth lasers.

“…From 2020 to 2021, the research group will improve the anti-noise capability and imaging signal-tonoise ratio of the GISC spectroscopic camera through the optimized design of the hyper-Rayleigh speckle field and polarization characteristics [17]; [18]. In this paper, 532 and 650 nm solid-state lasers are used as the light source [19], and the GISC snapshot spectroscopic camera is used to realize the accurate identification of the target and carry out experimental research work.…”

Aiming at the application requirements of spectral imaging technology in satellite remote sensing, biomedical diagnosis, marine detection and rescue, agricultural and forestry monitoring and classification, military camouflage identification, etc., this paper uses 532 and 650 nm lasers as light sources, and uses multi-spectral intensity correlation imaging equipment—snapshot spectroscopic cameras based on ghost imaging via sparsity constraints (GISC) enable precise identification of targets. In this paper, the principle of snapshot GISC spectral imaging is expounded, and the experimental research work of GISC spectral imaging target recognition technology based on active laser illumination is carried out. The experimental results show that using a 532 nm laser as the light source to illuminate the target object can accurately identify the green target letter “I”; using a 650 nm laser as the light source to illuminate the target object can accurately identify the red target letter “Q”. And gives spectral imaging results of the color target “QIT” acquired by the GISC spectroscopic camera through a single exposure at the wavelength range from 446 to 698nm, with both pseudo-color map and color fusion map. In order to further illustrate the feasibility of the experiment, the spectral distribution of the reconstructed image is analyzed, which has important practical significance and engineering value.

“…e generation of SLM lasers is usually based on a combination of the linewidth of the gain medium and the losses of the cavity. Alternatively, SLM selection methods can be applied to solid state lasers to generate SLM lasers [6,7]. Owing to their strong power (average and peak) scaling ability and wide range of wavelength coverage, solid-state lasers play an important role in space exploration, defense, and manufacturing [8][9][10].…”

Lasers with narrow linewidths and single frequencies are widely used in fields such as radar detection, nonlinear optics, and precision measurements. The demand for such lasers has promoted the rapid development of single-longitudinal-mode (SLM) selection technology. Here, we highlight the working principles of current mainstream SLM selection technologies and the recent advances in the field. We compare the characteristics of different SLM selection methods and list the challenges faced by these technologies.
