When you need a NLO crystal for type II SHG (o+e→e), and a NLO crystal for type II THG (o+e→e), the  out put polarization from SHG can not be used for THG. So you must  turn the polarization to get two perpendicular polarization for type II THG. Dual wavelength waveplate works like a polarizing rotator, it can rotate the polarization of one beam and remain another beam's polarization. Also the dual wavelength waveplate can be applied to following systems：          •   Type II SHG + Type II THG         •   Type II SHG + Type I THG         •   Type I SHG  + Type I THG    For example: we use KTP as SHG type II and LBO as THG type II, but the polarization of output beam from KTP is not optimized for THG type II. When we use a dual wavelength waveplate as drawing, it can change the 532nm beam to a special angle polarization but not change 1064nm beam at all.     Specifications： Material Crystal Quartz Diameter Tolerance +0/-0.25mm Clear Aperture ≥ central 90%  of  diameter Retardance Accuracy ＜λ/100 Surface Quality 20/10 Wavefront  Distortion λ/10 @ 632.8nm over the clear aperture Parallelism ≤3″ Coating Laser Line V AR Coating  R<0.25%< span=""> Damage Threshold 2MW/cm2,2J/cm2，10ns     Standard Retardation： Wavelength 1-Wavelength2  W1064-W532(nm)  W1064-W532(nm) W532-W266(nm) W532-W355(nm) Retardation 1-Retardation2 λ-λ/2 λ/2-λ λ/4-λ/2 λ/2-λ/4 Note：    •  Custom designs for other sizes ,coatings and holders are also available upon request.    •  MT-OPTICS's standard coatings are available upon request.   Category:Polarization Optics/ Waveplates
