The Melar series, developed by Beamtech Optronics, offers high-energy and high-beam-quality laser sources at 1053nm, 527nm, and 351nm wavelengths. In 2005, Beamtech Optronics successfully built a nanosecond Nd:glass laser system for the Institute of Physics, Chinese Academy of Sciences, with an output of 100J at 527nm , pulse width 15ns, used to pump a Ti:sapphire femtosecond laser amplifier. Between 2008 and 2024, Beamtech Optronics continued to develop 20J, 50J, and 80J high-energy Nd:glass laser systems for research institutions such as the Xi'an Institute of Optics and Precision Mechanics, the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, and Shenzhen University, for various scientific applications.
The Melar series offers energy outputs of 20J, 50J, 80J, and 100J at 1053nm with uniform spatial beam distribution. It can achieve pulse repetition rates of 20 minutes per pulse, 10 minutes per pulse, and 5 minutes per pulse. Optional second harmonic (527nm) and third harmonic (351nm) modules are available. The conversion efficiency of third harmonic reaching up to 40%. We provide customizable laser solutions for scientific research.
The Melar series is suitable for a wide range of scientific applications, including pumping Ti:sapphire , laser-matter interaction studies, and optical component damage detection and pre-treatment. In the field of high-energy pulsed lasers, Beamtech Optronics has many years of technical development and engineering experience, and can provide users with a variety of customized laser solutions.

MELAR can provide high-energy green pump light for the main amplification stage of high-power Ti CPA systems. The system is suitable for applications requiring several joules to tens of joules of pump energy and can also be configured with a single-frequency square-wave seed source for OPCPA pumping.
The combination of high single-pulse energy, nanosecond pulse duration and controlled beam distribution makes the MELAR series suitable for laser–matter interaction research and other high-peak-power laboratory experiments.
MELAR systems can be used for laser-induced damage threshold testing, optical component pretreatment and research involving the response of optical materials under high-energy laser irradiation.
The high pulse energy and focusable beam make selected MELAR configurations suitable for laser shock peening research and process development.
MELAR is an engineered laser platform rather than a single fixed configuration. Beamtech can customize the following parameters according to the customer’s experimental requirements:
◆ Fundamental or harmonic output wavelength
◆ Pulse energy and pulse duration
◆ Shot interval
◆ Beam diameter and focal spot requirements
◆ Spatial energy distribution
◆ Harmonic conversion module
◆ Seed injection configuration
◆ Optical layout and system integration
◆ Control and safety interfaces
To recommend a suitable configuration, Beamtech’s engineering team evaluates the required wavelength, target pulse energy, beam profile, repetition interval, application fluence and available installation space.
Beamtech has developed high-energy Nd laser systems for scientific research institutions since 2005. An early system delivered to the Institute of Physics, Chinese Academy of Sciences, produced 100 J at 527 nm with a pulse duration of 15 ns and was used to pump a Ti femtosecond laser amplifier.
Between 2008 and 2024, Beamtech continued to develop 20 J, 50 J and 80 J Nd laser systems for research institutions including the Xi’an Institute of Optics and Precision Mechanics, the Shanghai Institute of Optics and Fine Mechanics, and Shenzhen University.
A recently delivered 50 J system achieved stable energy output and a uniform focused beam. See the 50 J Nd laser installation and acceptance results.
