“…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.

“…High-power lasers with high beam quality are of interest for applications such as material processing, space exploration, defence, and high-energy physics [1][2][3]. However, the negative effects, including thermal lens, birefringence, beam distortion, and spectral broadening caused by the intensified thermal accumulation in the laser media during power scaling, limit improvements to its performance [4][5][6].…”

“…In the last decade, diamond has been of interest to the laser community due to its excellent thermophysical, spectral, and nonlinear optic properties. By using a single crystal diamond with a volume of less than 0.04 cm 3 , over a kilowatt of quasi-continuous Raman laser power (in thermal quasi-steady-state) [18,19] and high power (11 W for continuouswave, and on-time power 40 W for quasi-continuous-wave) Brillouin lasing [20,21] have been demonstrated. In addition, lasers based on diamond as the gain medium provide a promising approach to high brightness beam generation [22,23] with a wide spectral range [24][25][26].…”

Despite their extremely high thermal conductivity and low thermal expansion coefficients, thermal effects in diamond are still observed in high-power diamond Raman lasers, which proposes a challenge to their power scaling. Here, the dynamics of temperature gradient and stress distribution in the diamond are numerically simulated under different pump conditions. With a pump radius of 100 μm and an absorption power of up to 200 W (corresponding to the output power in kilowatt level), the establishment period of thermal steady-state in a millimeter diamond is only 50 μs, with the overall thermal-induced deformation of the diamond being less than 2.5 μm. The relationship between the deformation of diamond and the stability of the Raman cavity is also studied. These results provide a method to better optimize the diamond Raman laser performance at output powers up to kilowatt-level.

“…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]. In the past few decades, there has been a rise in interest towards the SLM selection of solidstate lasers, which also promotes the development of optical components, cavity structures, and active controllers.…”

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.
