The wedge enables to change the cavity length by a small amount to fine tune the spectral cavity mode position over the full gain bandwidth of Nd:YVO4 and hence to optimize the output power. This additional degree of freedom may be a suitable approach to increase the wafer scale mass production yield or also to simplify frequency tuning of CW single-frequency microchip lasers.enghttps://www.osapublishing.org/library/license_v1.cfm530CrystalsDegrees of freedom (mechanics)Picosecond lasersQ switchingDegree of freedomFrequency-tuningMass productionMicrochip lasersNd:YVO4 crystalsPassively Q-switchedSingle frequencyWavelength tuningMicroprocessor chipsWedged Nd:YVO4 crystal for wavelength tuning of monolithic passively Q-switched picosecond microchip lasersArticle
