Diode-end-pumped electro-optically Q-switched Nd:YAG single crystal fiber for direct high-energy laser generation
Crystal fiber is highly valued in high-power laser research due to its excellent thermo-optic property. In this paper, we report on the result of studying high-energy nanosecond pulse laser at 1064 nm using Nd:YAG single crystal fiber as gain medium based on electro-optic Q-switching. With a 808-nm continuous wave diode laser as pump source, we obtained an average output power of 6.06 W at a repetition rate of 500 Hz with a pulse width of 29 ns, corresponding to a pulse energy of 12.12 mJ, and a peak pulse power of 0.42 MW. To our knowledge, this is actually the first research combining electro-optic Q-switching technology and end-pumped crystal fiber laser technology, and the results have indicated that crystal fiber has advantages in improving laser performance for directly obtaining high pulse energy and peak power with less system complexity and cost.
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.
