1570nm single wavelength laser source Manufacturers

A revolutionary technology allows scientists to observe the interior of instantaneous particles called excitons (Exciton) at close range in an unparalleled way. Excitons describe the bound state of a pair of electrons and holes that are attracted to each other by electrostatic Coulomb interaction. They can be regarded as electrically neutral quasi-particles that exist in insulators, semiconductors and some liquids. They are condensed matter physics. The basic unit that transfers energy without transferring charge.

An optical fiber sensor is a sensor that converts the state of the measured object into a measurable light signal. The working principle of the optical fiber sensor is to send the incident light beam from the light source into the modulator through the optical fiber. The interaction between the modulator and the external measured parameters determines the optical properties of the light, such as the intensity, wavelength, frequency, phase, polarization state, etc. It changes and becomes a modulated optical signal, which is then sent to the optoelectronic device through the optical fiber and passed through the demodulator to obtain the measured parameters. During the whole process, the light beam is introduced through the optical fiber, passes through the modulator, and then emitted. The role of the optical fiber is first to transmit the light beam, and secondly to act as an optical modulator.

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 laser diode chip is a semiconductor-based laser that consists of a P-N structure and is powered by current. The laser diode package is a complete device that is assembled and packaged together in a sealed package housing to form a semiconductor laser chip that emits coherent light, a monitoring photodiode chip for feedback control of power output, a temperature sensor chip for temperature monitoring, or an optical lens for laser collimation.
