Laser crystals for solid-state laser systems
ATR Crystal supplies laser crystals and passive Q-switch components for research and OEM laser systems. Material, dopant concentration, finished geometry and coating requirements can be reviewed against your specification.
Start with the crystal’s role in your cavity. The gain medium, Q-switch and bonded structure each need different information for quotation. Use the material references below to identify the product page that matches your design.
Browse the laser crystal materials for product specifications and available geometries.
Select the crystal by its role in the cavity
These materials serve different functions. Choose the gain crystal and any passive Q-switch or bonded sections together with the pump source and cavity requirements.
| Material or component | Role in the laser design | Details to specify |
|---|---|---|
| Nd:YAG laser crystals | Gain medium for continuous-wave, pulsed and Q-switched solid-state lasers. | Nd concentration, rod or slab dimensions, pump wavelength and coating requirements. |
| Nd:YVO4 laser crystals | Gain medium for compact diode-pumped laser cavities. | Crystal cut, polarization, dopant concentration, dimensions and coatings. |
| Yb:YAG laser crystals | Gain medium for diode-pumped and ultrafast laser designs. | Yb concentration, geometry, pump wavelength and cooling arrangement. |
| Cr:YAG passive Q-switch crystals | Saturable absorber for passive Q-switching. | Initial transmission at the operating wavelength, clear aperture, thickness and coatings. |
| Ti:Sapphire laser crystals | Tunable gain medium for spectroscopy and ultrafast research lasers. | Pump absorption, figure of merit, crystal orientation, end geometry and coatings. |
| Er:YAG laser crystals | Gain medium for Er:YAG laser systems. | Er concentration, dimensions, pump configuration, surface requirements and coatings. |
| Diffusion bonded laser crystals | Composite components combining a gain crystal with end caps or a passive Q-switch section. | Material sequence, segment lengths, dopant levels, interface requirements and a drawing. |
Application requirements to review
Industrial and diode-pumped lasers
For marking, machining or laboratory diode-pumped lasers, identify the gain material and operating mode before specifying a crystal. Continuous-wave and pulsed cavities can require different dimensions and coatings. Include the pump arrangement and cooling method so that the quotation reflects the intended installation.
Passively Q-switched laser systems
Cr:YAG is the passive Q-switch component. Specify its initial transmission at the operating wavelength and the clear aperture required by your beam. Review these details with the gain crystal and cavity design. Pulse energy and duration depend on the assembled laser system.
Tunable and ultrafast research lasers
For Ti:Sapphire, provide the pump wavelength, target laser wavelength range and end-face configuration. State how pump absorption and figure of merit should be measured. For Yb:YAG projects, include the geometry and cooling arrangement required by the laser design.
Er:YAG components for OEM laser systems
Specify the Er concentration, crystal dimensions and optical coatings for your Er:YAG cavity. Include the pump method and mechanical drawing where available. The quotation covers the crystal component and agreed inspection criteria; complete equipment performance is evaluated by the system designer.
Bonded crystal assemblies
For a diffusion bonded crystal, show the material sequence and each segment’s length on the drawing. Identify the doped sections and any passive Q-switch section. Bonding interfaces, orientation and finished dimensions should be defined before comparing quotations.
Request a quotation for your laser crystal
Send the specification you have, including any requirements that remain undecided. The following information helps define the material, machining and coating scope.
| Quotation item | Information to provide |
|---|---|
| Material and function | Crystal material and its role as a gain medium, passive Q-switch or bonded component. |
| Doping or absorption requirement | Dopant concentration; for Cr:YAG, initial transmission at the operating wavelength; for Ti:Sapphire, pump absorption and FOM requirements. |
| Geometry and orientation | Finished dimensions, crystal cut or orientation, clear aperture, tolerances and a drawing. |
| Pump and laser conditions | Pump wavelength, laser wavelength, operating mode and cooling arrangement. |
| Surface finish and coatings | Polished faces, flatness, surface quality, AR/HR coating wavelengths and any required test method. |
| Order and inspection | Quantity, delivery destination, requested schedule and acceptance or inspection requirements. |
Surface quality, coating performance and damage-threshold requirements should be agreed for the specified component and test conditions. Final specifications and acceptance criteria are confirmed in the quotation.

Technical guides for material selection
The laser crystal selection guide compares gain materials and passive Q-switch components. For a pump-specific Nd:YAG project, read the Nd:YAG crystal guide for 808 nm pumping before finalizing doping, length and coatings.
