532nm 1064nm Picosecond Pulse Fiber Laser Manufacturers

The traditional laser uses the thermal accumulation of laser energy to melt and even volatilize the material in the active area. In the process, a large number of chips, micro-cracks and other processing defects will be generated, and the longer the laser lasts, the greater the damage to the material. The ultra-short pulse laser has an ultra-short interaction time with the material, and the single-pulse energy is super strong enough to ionize any material, realize non-hot-melt cold processing, and obtain the ultra-fine, low-damage processing advantages incomparable with long-pulse laser. At the same time, for the selection of materials, ultrafast lasers have wider applicability, which can be applied to metals, TBC coatings, composite materials, etc.

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.

Single-frequency fiber lasers have unique properties such as ultra-narrow linewidth, adjustable frequency, ultra-long coherence length, and ultra-low noise. The FMCW technology on microwave radar can be used for ultra-high-precision coherent detection of ultra-long-distance targets. Change the market's inherent concepts of fiber sensing, lidar and laser ranging, and continue to carry out the revolution in laser applications to the end.
