Product Parameter Advantages and Applications

  • Outstanding Stability: Co2+:MgAl2O4 crystal is known for its exceptional stability, suitable for applications in eye-safe lasers and medical lasers.

  • Wide Band Absorption: With wide band absorption characteristics, it covers the laser wavelength range from 1.2 to 1.6 micrometers, particularly suitable for 1.54-micrometer Er:glass lasers, as well as 1.44 and 1.34 micrometer wavelengths.

  • High Absorption Cross Section: With an absorption cross-section as high as 3.5×10-19 cm2, passive Q-switching of Er:glass lasers can be achieved without the need for intracavity focusing, whether using flash lamps or diode laser pumping.

  • Rare Excited Absorption: Virtually no excited-state absorption ensures high contrast Q-switching, with the ratio of initial (small signal) absorption to saturated absorption being greater than 10.

  • Evenly Distributed Cobalt Ions: Cobalt ions readily substitute magnesium ions in the crystal without the need for additional charge-compensation ions.

  • Long Excited State Lifetime: Long excited-state lifetime contributes to stable laser output.

Key Applications

  1. Radar and Ranging Lasers: Suitable for 1.35-micrometer Er:Glass lasers, enabling passive Q-switching.

  2. Medical Lasers: Widely used in medical laser systems operating at 1,500 micrometers, providing high-performance passive Q-switching.
