532nm 1064nm Picosecond Pulse Fiber Laser Manufacturers

The output power of the first fiber laser was only a few milliwatts. Recently, fiber lasers have developed rapidly, and high-power fiber amplifiers have been obtained. In particular, the output power of the amplifiers can reach tens of hundreds of watts, even in some single-mode fibers. on kilowatts. This is due to the large surface area to volume ratio of the fiber (to avoid excess heat) and the guided wave (waveguide) nature, which avoids the problem of thermo-optic effects at very high temperatures. Fiber laser technology is very competitive with other high-power solid-state lasers, thin-disk lasers, etc.

Everyone must have heard the slogan "femtosecond laser for myopia", but I believe many people don't know what femtosecond laser is. Similarly, there are nanosecond laser and picosecond laser. What's the difference between these strange seconds and our common lasers?

Lidar (Laser Radar) is a radar system that emits a laser beam to detect the position and speed of a target. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, you can obtain relevant information about the target, such as Target distance, azimuth, altitude, speed, attitude, even shape and other parameters, so as to detect, track and identify aircraft, missiles and other targets. It consists of a laser transmitter, an optical receiver, a turntable, and an information processing system. The laser converts electrical pulses into light pulses and emits them. The optical receiver then restores the light pulses reflected from the target to electrical pulses and sends them to the display.

A pump laser is a laser used to provide an excitation light source for a fiber laser or fiber amplifier. The emission wavelength of a 980nm pump laser is approximately 980 nanometers (nm).

Box Optronics 760nm 10mW butterfly laser utilizes a multi-quantum well distributed feedback (MQW-DFB) structure, ensuring a precise and stable 760nm wavelength with a narrow linewidth of less than 2MHz.
