“…Lasers with narrow linewidth are in high demand because of their ability to exhibit high temporal and spatial coherence and low-phase noise, which are important for holography, high-resolution measurements and detections, laser spectroscopy, and optical communication. 42 Since the very first demonstrations of microdisk lasers based on colloidal nanomaterials, 43 photonic crystals, 44 and nanowires, 45 nanolasers have been quickly developed. 17,[46][47][48][49] Lasers from solution-processed materials can be operated under both electrical and optical pumping.…”

Solution processed semiconductors are in demand for present and next-generation optoelectronic technologies ranging from displays to quantum light sources because of their scalability and ease of integration into devices with diverse form factors. One of the central requirements of semiconductors used in all these applications is a narrow photoluminescence (PL) linewidth. Narrow emission linewidths are needed to ensure both color and single-photon purity, raising the question of what design rules are needed to obtain narrow emission from semiconductors made in solution. In this review we first examine the requirements for colloidal emitters for a variety of applications including light-emitting diodes, photodetectors, lasers, and quantum information science. Next, we will delve into the sources of spectral broadening, including homogeneous broadening from dynamical broadening mechanisms in single-particle spectra, heterogeneous broadening from static structural differences in ensemble spectra, and spectral diffusion. Then, we compare the current state of the art in terms of emission linewidth for a variety of colloidal materials including II-VI quantum dots (QDs) and nanoplatelets, III-V QDs, alloyed QDs, metal-halide perovskites including nanocrystals and 2D structures, doped nanocrystals, and, finally, as a point of comparison, organic molecules. We end with some conclusions and connections, with an outline of promising paths forward.

Narrow-linewidth lasers are in extensive demand for numerous cutting-edge applications. Such lasers operating at the visible range are of particular interest. Self-injection locking of a laser diode frequency to a high-Q whispering gallery mode is an effective and universal way to achieve superior laser performance. We demonstrate ultrastable lasing with less than 10 Hz instantaneous linewidth for 20 μs averaging time at 638 nm using a Fabry-Pérot laser diode locked to a crystalline MgF2 microresonator. The linewidth measured with a β-separation line technique that characterizes 10 ms stability is as low as 850 Hz. Output power exceeds 80 mW. Demonstrated results are among the best for compact visible-range lasers in terms of stability and output power. We additionally report the first demonstration of a gain-switched regime for such stabilized Fabry-Pérot laser diode showing a high-contrast visible frequency comb generation. Tunable linespacing from 10 MHz to 2 GHz is observed. We demonstrated that the beatnote between the lines has sub-Hz linewidth and experiences spectral purification in the self-injection locking regime. This result might be of special importance for spectroscopy in the visible range.

“…[1][2][3][4]. Across the domains of coherent optical communications, sodium guide star technology, gravitational wave detection, and non-linear optics, solid-state single-longitudinal-mode (SLM) laser sources with a narrow spectral bandwidth are attracting significant interest [5][6][7][8][9][10]. These lasers, which often also carry additional characteristics such as broad wavelength tuning capability, high pulse energy, and good beam quality, are enabling a host of new techniques and methodologies.…”

A compact solid-state single-longitudinal-mode (SLM) Q-switched laser based on a compound cavity is demonstrated. SLM operation is achieved through the enhancement of mode competition (via manipulation of the effective reflectivity of the resonator mirrors and intracavity field accumulation time) and does not require the use of a feedback loop. In this work, SLM emission with a linewidth of 254.3 MHz is demonstrated, and a high SLM ratio of up to 99.6% is achieved. The laser operates at a repetition rate of 10 Hz, producing 10 ns pulses with a pulse energy of 14.81 mJ.
