AI Overview
Co:Spinel (
) acts as a premier passive Q-switch for eye-safe
lasers, producing high-peak-power pulses at 1.54
m. Its high absorption cross-section (
) and low excited-state absorption allow efficient pulsed generation for rangefinders and LIDAR, often with compact designs.
Key Features and Benefits
- Optimal Wavelength: Perfectly matches the eye-safe 1540 nm (1.54 m) emission of Erbium-doped glass lasers.
- High Performance Q-Switch: Features low saturation intensity and negligible excited-state absorption, resulting in high contrast.
- Excellent Material Properties: is chemically stable, hard, and has high optical quality, allowing for robust operation.
- Efficient Pulsing: High absorption cross-section allows for, a high ratio of initial to saturated absorption.
- Bonding Options: can be bonded directly with Er:Yb:glass to enhance stability, reduce thermal effects, and minimize system size.
