Abstract

Narrow linewidth, high-brightness 2 μm pulsed lasers offer significant advantages for high-precision applications, including micromachining, medical treatments, and spectral analysis. This study presents the first successful demonstration of a Tm: YAG 2 μm pulsed laser, distinguished by its narrow linewidth and high brightness. The laser system incorporates an MXene Ti₃C₂Tx-based saturable absorber (SA), an acoustic-optic modulator (AOM), and a Fabry-Pérot (F-P) etalon. With a pump power of 10.17 W and a repetition rate of 5 kHz, the laser achieves a minimum pulse width of 148.8 ns, a peak power of 0.81 kW, an output central wavelength of 2014.00 nm, a linewidth of 0.24 nm, and beam quality factors of M² = 1.13.

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
