Fiber Grating Hygrometer Humidity Sensor Manufacturers

Laser distance measuring is measured using a laser as a light source.It is divided into continuous laser and pulse laser according to the mode of laser operation.Gas lasers like helium-neon, argon ion, krypton cadmium and so on work in a continuous output state for phase laser ranging, dual heterogeneous GaAs semiconductor laser for infrared ranging; solid laser such as ruby, neodymium glass, for pulse laser ranging.Laser rangefinder due to the characteristics of good monochromy and strong orientation of laser, coupled with the semiconductor integration of electronic lines, compared with the photoelectric rangefinder, it can not only work day and night, but also improve the rangefinder accuracy.

In today's era of rapid development of laser technology, solid-state lasers and fiber lasers, as the two major mainstream laser products, have each demonstrated their unique charm and advantages in many fields such as industrial production, scientific research, and military applications.

Lithography is a technique for transferring a designed pattern directly or through an intermediate medium onto a flat surface, excluding areas of the surface that do not require a pattern.

Operators are making efforts to build 5G base stations, and the demand for optical modules continues to expand. In 2019, my country has built more than 130,000 5G base stations. 2020 is the first year of large-scale construction of 5G base stations, which mainly cover urban areas. In 2020, 5G network construction will focus on more SA networking, with higher commercial value. During the two sessions in 2020, the Ministry of Industry and Information Technology stated that my country added more than 10,000 base stations every week. According to the operator's investment plan, the three major operators will build 700,000 base stations in September 2020, and the construction will not stop from September to December. With China Radio and Television as a new entrant, the joint construction of 700MHZ 5G base stations with China Mobile is expected to be further expanded.

Semiconductor saturable absorber mirror (SESAM) is the core device for mode-locking to generate ultrashort pulses, especially picosecond pulses. This is a nonlinear light absorption structure that combines a mirror structure and a saturable absorber. Relatively weak pulses can be suppressed, and the pulses can be attenuated in a way that reduces their duration. At present, with the development of microfabrication industry at home and abroad, the demand for ultrashort pulses, especially picosecond pulsed lasers, is increasing, and the demand for SESAM is also increasing.
