Wavelength division multiplexing refers to a technology in which signals of different wavelengths are transmitted together and separated again. At most, it is used in optical fiber communication to transmit data in multiple channels with slightly different wavelengths. Using this method can greatly improve the transmission capacity of the optical fiber link, and the use efficiency can be improved by combining active devices such as optical fiber amplifiers. In addition to applications in telecommunications, wavelength division multiplexing can also be applied to the case where a single fiber controls multiple fiber optic sensors.

Compared with traditional technologies, the advantages of fiber lasers in beam quality, depth of focus and dynamic parameter adjustment performance have been fully recognized. Coupled with the advantages of electro-optical conversion efficiency, process versatility, reliability and cost, the application level of fiber lasers in medical device manufacturing (especially in fine cutting and micro welding) has been continuously improved.

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.

In the mid-1980s, Beklemyshev, Allrn and other scientists combined laser technology and cleaning technology for practical work needs and conducted related research. Since then, the technical concept of laser cleaning (Laser Cleanning) was born. It is well known that the relationship between pollutants and substrates The binding force is divided into covalent bond, double dipole, capillary action and van der Waals force. If this force can be overcome or destroyed, the effect of decontamination will be achieved.

The gain medium of an optical amplifier can only achieve a limited gain. One approach achieves higher gain by geometrically setting up light so that it passes through multiple channels as it passes through the amplifier, known as a multipass amplifier. The simplest is a two-pass amplifier, where the beam passes through the crystal twice, usually with exactly or nearly opposite directions of propagation.
