aggas2 crystal (ags crystal)

aggas2 crystal is transparent from 0.5 to 13.2um. aggas2 crystal has been demonstrated to be an efficient frequency doubling crystal for infrared radiation, such as the 10.6 µm output of CO₂ lasers. Silver Gallium Sulfide (aggas2, AGS) is very useful for middle and deep infrared applications due to its large nonlinear optical (NLO) coefficients and high transmission in the IR region. thin aggas2 crystal plates are very popular for ultrashort pulse generation in mid IR range by difference frequency employing NIR wave length pulses.

Dimension:

standard cross section are 8*8mm,  5*5mm, crystal length ranges from 0.1 to 30mm. Custom sizes or coating are available on request.

Application:

• Generation second harmonics on CO and CO₂ - lasers
• Optical parametric oscilator
• 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 (OPO pumped by Nd:YAG and others lasers operating in 1200 to 10000 nm region with efficiency 0.1 to 10 %)
• Optical narrow-band filters in the region near isotropic point (0.4974 m at 300 °K), transmission band being tuned at temperature variation
• Up-conversion of CO₂ laser radiation image into near-IR or visible region by using/ or use of Nd:YAG, ruby or dye lasers with efficiency up to 30 %
