An ultrafast laser is a type of laser that operates based on mode-locking techniques such as Semiconductor Optical Amplifier (SOA) or Semiconductor saturable absorber mirror (SESAM), and Kerr-lens mode-locking, producing pulses with widths in the picosecond (ps) or even femtosecond (fs) range. These lasers are also referred to as ultra-short pulse lasers.Dechuang Laser manufactures ultrafast lasers that include those operating at the femtosecond level with wavelengths of 1550nm, 1030nm, and 780nm, as well as those operating at the picosecond level with wavelengths of 1064nm and 532nm.
