Ultrafast Laser System is that emits ultrashort pulses of light, generally of the order of femtoseconds to one picosecond.Popular ultrafast lasers on the market includes titannium doped sapphire (Ti:Sapphire) lasers, neodymium-doped YAG (Nd:YAG) or ytterbium-doped (Yb:YAG) lasers and the Yb doped fiber lasers. Once the Ultrafast laser pulses is generated, it is necessary to propagate these pulses without disturbing the temporal beam profile, then some special optical component with low despersion become critical for this kind of lasers: Ultrathin BBO crystal, Ultrathin LBO crystal, Thin windows, Low Group Delay Dispersion (GDD) mirrors, Dispersion prisms and Time Delay Compensators.
