Name: Infrared Nonlinear Crystal - AgGaS2 (AGS)
Brand: DIEN TECH
Availability: InStock

Description

AGS is transparent from 0.50 to 13.2 µm. Although its nonlinear optical coefficient is the lowest among the mentioned infrared crystals, high short wavelength transparency edging at 550 nm is made use of in OPOs pumped by Nd:YAG laser; in numerous difference frequency mixing experiments with diode, Ti:Sapphire, Nd:YAG and IR dye lasers covering 3–12 µm range; in direct infrared countermeasure systems, and for SHG of CO2 laser. Thin AgGaS2 (AGS) crystal plates are popular for ultrashort pulse generation in mid IR range by difference frequency generation employing NIR wavelength pulses.

Frequently Asked Questions

What is AGS?

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

What are the applications of AGS?

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.

What are the dimensions of AGS?

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.

What are the technical parameters of AGS?

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.

What is the transmission spectra of AGS?

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.
