Component Specifications

Definition
A specialized mechanical component designed to securely hold optical crystals (such as Nd:YAG, KTP, or BBO) within optical mounts or housings. It provides precise alignment, thermal management, and vibration damping to maintain crystal stability during laser operation, ensuring consistent optical performance and beam quality.
Working Principle
The clamp applies controlled mechanical pressure to hold the crystal in place while minimizing stress-induced birefringence. It often incorporates thermal interfaces for heat dissipation and kinematic mounting features for precise angular and positional adjustment. Some designs use spring-loaded mechanisms or differential screws for fine pressure control.
Materials
Typically made from aluminum alloys (6061-T6, 7075) for lightweight rigidity, stainless steel (304, 316) for corrosion resistance, or invar for thermal stability. Contact surfaces may include indium foil, silicone pads, or ceramic coatings to prevent damage to crystal surfaces.
Technical Parameters
  • Clamping Force 5-50 N (adjustable)
  • Surface Flatness <λ/10 @ 633nm
  • Temperature Range -40°C to +150°C
  • Vibration Damping >90% at 100Hz
  • Thermal Conductivity >100 W/m·K (interface)
Standards
ISO 10110, ISO 14999, DIN 3140

Frequently Asked Questions

How does the clamp prevent damage to delicate crystal surfaces?

It uses compliant interface materials (like indium foil or silicone) and controlled pressure distribution to avoid point loading and surface deformation.

Can the same clamp accommodate different crystal sizes?

Many designs feature adjustable jaws or interchangeable inserts to accommodate crystals from 5mm to 50mm dimensions.

How does thermal management work in these clamps?

They incorporate high-conductivity materials and often have integrated cooling channels or Peltier interfaces to dissipate heat from the crystal.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
