The present disclosure provides an ultrafast laser that outputs multiple wavelengths. The ultrafast laser includes a fundamental frequency ultrafast laser unit, an optical beam splitting and polarization controlling unit, a multiple frequency unit, and an optical beam combining unit. The fundamental frequency ultrafast laser generates a multiple frequency ultrafast laser by the multiple frequency unit, such as double frequency light, triple frequency light, etc., and the optical beam combining unit makes the fundamental frequency light and the double frequency light output in a light outlet, the controlling unit controls the wavelength of the laser of the light outlet by controlling the polarization state of the laser. The ultrafast laser of the present disclosure can realize fast switching output among the fundamental frequency light and multiple frequency light, and output of combined pulse fundamental frequency light and double frequency light. The present disclosure also provides a strong powerful laser tool.

Ultrafast laser

An all-fiber airtight packaging structure with semiconductor saturable absorber mirror includes a ceramic optical fiber ferrule connector, a SESAM, a SESAM fixed block, a TEC chilling plate, a sealing shell, and a cover plate. The cover plate seals the sealing shell by connecting to a sealing shell surface. The TEC chilling plate and the SESAM fixed block are set in the sealing shell. The SESAM fixed block is located above the TEC chilling plate. The SESAM is pasted on the SESAM fixed block. A sealing shell central hole is defined in the sealing shell. The ceramic optical fiber ferrule connector is entered into the sealing shell through the sealing shell central hole, and an output end of ceramic optical fiber ferrule connector is opposited to an end of SESAM which is mounted on the SESAM fixed block.
