532nm 1064nm Picosecond Pulse Fiber Laser Manufacturers

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.

High power ultrafast lasers are widely used because of their short pulse duration and peak power.Ultrafast lasers are used in material processing applications, medical fiber lasers, microscopy and other fields.

The near-infrared spectrum is mainly generated when the molecular vibration transitions from the ground state to a high energy level due to the non-resonant nature of the molecular vibration. What is recorded is mainly the frequency doubling and combined frequency absorption of the vibration of the hydrogen-containing group X-H (X=C, N, O). . Different groups (such as methyl, methylene, benzene rings, etc.) or the same group have obvious differences in the near-infrared absorption wavelength and intensity in different chemical environments.

At present, China has become the world's largest manufacturing country, and the domestic market has an increasingly strong demand for laser technology products. Since 2010, thanks to the continuous expansion of the laser processing application market, China's laser industry has gradually entered a period of rapid development. In 2018, the scale of China's laser equipment market reached 60.5 billion yuan, a year-on-year increase of 22.22%, and the compound growth rate from 2011 to 2018 reached 26.45%. China Business Industry Research Institute predicts that China's laser equipment market will reach 98.8 billion yuan in 2021.
