Chromium Doped Yttrium Aluminum Garnet (Cr4+:YAG)

Chromium Doped Yttrium Aluminum Garnet (Cr4+: YAG) is a solid state laser active material and broadly tunable in the near infrared spectral region (1.35 - 1.57 mm) which makes it attractive for many applications in optical fiber communications, laser remote sensing, eye-safe ranging and others. Its broad absorption band offers a variety of possible pump sources including Nd:YAG lasers and InGaAs diode lasers.
