Web1 de fev. de 2009 · In this letter, in order to get high power and high beam quality second harmonic generation, a V-shaped system is designed which can compensate for astigmatism by adopting the appropriate fold angle. An average power of 185 W is obtained at 532 nm with a pulse width of 180 ns and a repetition rate of 10 kHz. WebOSTI.GOV Journal Article: High average power harmonic generation ...

High average power harmonic generation - IEEE Xplore

WebHá 7 horas · In this paper, the stabilization and high efficiency of an unstable Second Harmonic Generation (SHG) of an Nd:YVO4 laser with a KTP intracavity is demonstrated. By using a passive Q-switching crystal (Cr4+:YAG) and a parametric modulation method (harmonic modulation), the stabilization of the laser is reached. An harmonic … WebHigh average power is achieved by configuring the nonlinear material as a set of thin plates with a large ratio of surface area to volume, and cooling the exposed surfaces with a flowing gas. The design and material fabrication of such a harmonic generator is … rbs nearest branch
