General Description

Bonding Laser Crystals are cutting-edge materials engineered to reduce thermal effects in laser systems, especially in high-power solid-state lasers. These crystals are created by bonding multiple laser materials to achieve superior thermal management and structural compactness. This process enhances thermal conductivity and reduces thermal lensing, improving the beam quality and overall efficiency of the laser system. Bonding Laser Crystals are available in various configurations, including Nd:YVO4+YVO4, YAG+Nd:YAG, Yb:YAG+YAG, and others, ensuring flexibility for diverse laser applications.

These materials are specifically designed to meet the thermal management requirements of solid-state lasers without compromising performance. The bonding technology ensures minimal strain at the interface, providing excellent optical performance and longevity, making them ideal for applications in scientific research, medical devices, and industrial manufacturing.

Coating Specification

  • Anti-Reflective Coatings: For wavelengths 1.03–1.06 µm, reflectance <0.2%.
  • High-Damage Threshold Coatings: Suitable for high-power laser applications.
  • Custom Coating Options: Available upon request for specialized wavelength ranges or environmental conditions.
  • Adhesion Test: Compliant with MIL-C-675C military standards, an adhesion test involved applying a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed fully and then removed vertically. This procedure was performed three times, resulting in no blistering or peeling.
  • Temperature Test: In line with MIL-C-675C specifications, test pieces were subjected to temperatures of -62±1℃ and 71±1℃. After maintaining them at room temperature (16℃~32℃) for two hours, the adhesion test was repeated, confirming no film detachment.
  • Abrasion Resistance Test: Conforming to MIL-C-675C and CCC-C-440 standards, the abrasion resistance test involved a gauze tester applying a minimum force of 1.0 lbs (0.45 kg) to the film. This was repeated 25 times with gauze widths of 1/4 inch (6.4mm) and 3/8 inch (9.5mm), ensuring no damage occurred to the film surface.
  • Humidity Test: Under MIL-C-675C criteria, the test piece was placed in a controlled temperature and humidity chamber set to 49 ±2℃ and 95%~100% humidity for 24 hours. The film remained intact, with no peeling, scratches, or other defects.
  • Solvent and Cleaning Testing: Following MIL-C-675C specifications, test pieces were exposed to room temperature conditions (16℃~32℃) and tested with acetone and alcohol for at least 10 minutes each. After air drying and subsequent cleaning with a cotton cloth soaked in alcohol, the film surface showed no signs of peeling or scratches.
  • Salt Spray Test: After 100 hours in a 35°C environment with a 5% saltwater concentration, the film showed no signs of damage.
