A gas detection laser is an instrument that uses laser technology to measure gas concentration. It emits a laser beam into the gas and then analyzes the absorption or scattering of the laser beam to infer the gas concentration. This method has high sensitivity and accuracy, and can achieve rapid, online monitoring of specific gases.

Laser-a device capable of emitting laser light. The first microwave quantum amplifier was made in 1954, and a highly coherent microwave beam was obtained. In 1958, A.L. Xiaoluo and C.H. Towns extended the principle of microwave quantum amplifier to the optical frequency range. In 1960, T.H. Mayman and others made the first ruby laser. In 1961, A. Jia Wen and others made a helium-neon laser. In 1962, R.N. Hall and others created a gallium arsenide semiconductor laser. In the future, there will be more and more types of lasers. According to the working medium, lasers can be divided into four categories: gas lasers, solid lasers, semiconductor lasers and dye lasers. Free electron lasers have also been developed recently. High-power lasers are usually pulsed output.

The main oscillator fiber amplifier (MOFA, MOPFA or fiber MOPA) is different from the main oscillator power amplifier (MOPA), which means that the power amplifier in the system is a fiber amplifier. The latter are usually high-power pumped cladding amplifiers, commonly produced using ytterbium-doped fibers.

Semiconductor laser is a kind of laser developed in the 1960s, using semiconductor materials as working materials. Since the end of the 1970s, semiconductor lasers have clearly developed in two directions. One type is information-type lasers for the purpose of transmitting information, and the other type is power-type lasers for the purpose of directly using the optical power of the output laser.

It works stably, has a 12-month warranty, and accepts small and large batch orders. It can be used in R&D, medical and industrial fields.
