Laser welding technology is a technique of fusion welding, which uses a laser beam as an energy source to impact the weldment joint to achieve the purpose of welding.

GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interface, etc. Most operators regard it as an ideal technology for achieving broadband and integrated transformation of access network servic...

A fiber laser refers to a laser using a rare earth-doped glass fiber as a gain medium. The fiber laser can be developed on the basis of a fiber amplifier: under the action of pump light, a high power density is easily formed in the fiber, resulting in a laser of the laser working substance. The energy level "particle number inversion" can form a laser oscillation output when a ...

The sensor is a detecting device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information transmission, processing, storage and display. Requirements for recording, control and control.

The successful development of Lock Martin‘s latest 30,000 watt laser weapon can not be separated from the emergence and significant development of fiber laser technology. Fiber laser is a kind of laser which uses rare earth doped glass fiber as gain medium. Fiber laser can be developed on the basis of fiber amplifier. Different from the traditional gas laser, the fiber laser u...

The fiber laser uses a rare earth doped fiber as the gain medium, and the pump light forms a high power density in the core, resulting in a "particle number reversal" of the doped ion level. When a positive feedback loop (constituting a resonant cavity) is properly added, A laser output is produced.

The fiber optic temperature sensor is a sensing device that analyzes the spectrum of the fiber transmission to understand the real-time temperature by using the principle that the spectrum absorbed by some substances changes with temperature.

The pressure sensor has a measuring range that is twice as large as an inductive sensor. Not only can metal targets be detected, but also dielectrics such as paper, glass, wood and plastic, and even wall or paper. There are also trembling measurements and burglar alarms for humans, since the human body is equivalent to an electrical conductor at low frequencies.
