Femtosecond Laser Apparatus and Femtosecond Laser System including the same to improve the beam alignment

摘要

provides a femtosecond laser and femtosecond laser systems with them for improving the alignment properties of the beam . Femtosecond laser device comprises a first laser medium and the second laser medium disposed to face each other ; The first and second laser medium of claim 1 disposed so as to each incident pumping light in the laser medium and the second laser diode laser diode ; And is disposed between said first laser medium and the second laser medium , the first and could not be absorbed in the second hole and the first and second laser medium for the laser beam is generated from the pumping light passes through the laser medium the damper includes a block or beam having a beam absorption formed on the periphery of the hole to absorb . ;
