Beschreibung
Zusammenfassung:	The utility model relates to an accurate phase match basic mode third harmonic conversion equipment based on optic fibre, including the first laser instrument that produces fundamental frequency laser, produce the second laser instrument of reverse transmission's laser pulse sequence, fundamental frequency laser that first laser instrument produced produces basic mode third harmonic to the transmission before in optic fibre, and the second laser instrument is leading -in to have the same center wavelength's reverse transmission's laser pulse sequence with fundamental frequency laser. The utility model discloses make the harmonic obtain effective the growth along transmission direction, harmonic conversion efficiency is showing and is improving. The device provided by the utility model can realize accurate phase match between the basic mode of the basic mode of base frequency and frequency tripling to obtain the output of basic mode third harmonic, the frequency multiplier can be directly and other general opt
