Frequently Asked Questions

AGS is an infrared nonlinear crystal that is transparent from 0.50 to 13.2 µm.

AGS can be used for generation of second harmonics on CO and CO2 lasers, optical parametric oscillator, different frequency generator to middle infrared regions up to 12 mkm, frequency mixing in the middle IR region from 4.0 to 18.3 µm, tuneable solid state lasers, optical narrow-band filters, and up-conversion of CO2 laser radiation image into near-IR or visible region.

The standard cross-sections of AGS are 8x8mm and 5x5mm, and the crystal length ranges from 1 to 30mm. Custom sizes are also available on request.

The technical parameters of AGS include wavefront distortion less than λ/6@633nm, dimension tolerance of (W+/-0.1mm)x(H+/-0.1mm)x(L+0.2mm/-0.1mm), clear aperture of >90% central area, flatness of λ/6@633nm for T>=1.0mm, surface quality of scratch/dig20/10 per MIL-O-13830A, parallelism better than 1 arcmin, perpendicularity of 5 arcminutes, and angle tolerance of Δθ<+/-0.25o, Δφ<+/-0.25o.

AGS displays excellent bulk quality across the transmission range, except for residual array absorption centered near 1.8um. The phase matching and nonlinear optical properties of AGS allow various SFM/DFM interactions from the visible to Middle infrared.
