Lithium niobate crystal substrates are susceptible to optical damage under high-intensity illumination, which can be mitigated by MgO doping. The substrate surface roughness below 5 Å requires clean-room handling to avoid contamination and scratches that degrade optical performance.
- Optical Damage Threshold: MgO doping is recommended to improve the optical damage threshold for high-power applications.
- Surface Sensitivity: Polished surfaces with roughness below 5 Å require particle-free handling to maintain optical quality.
Inspect each substrate upon receipt for visible defects such as chips or scratches under a bright light. Store substrates in a clean, dry container at room temperature away from direct UV exposure to prevent surface degradation.
Required Equipment: Clean-room gloves, Anti-static tweezers, Nitrogen dust-off gun
- Inspect Substrate
Inspect the substrate under a bright light for chips, scratches, or dust particles before any handling. - Clean Surface
Use a nitrogen dust-off gun to remove loose particles from the polished surface before use. - Transfer Substrate
Transfer the substrate using anti-static tweezers, gripping only the unpolished edges to avoid damage.
What is the surface roughness specification for the ATOMFAIR Lithium Niobate Crystal Substrate 5x5x0.5 mm (0001)?
The surface roughness is specified as less than 5 Å. This ultra-smooth finish is critical for minimizing scattering losses in nonlinear optical and electro-optic applications such as parametric oscillators and optical modulators.
Does the ATOMFAIR LiNbO3 substrate (5x5x0.5 mm, (0001)) support MgO doping for improved optical damage threshold?
Yes, MgO doping is listed as a way to improve the optical damage threshold. This is particularly important for high-power frequency doubling and acousto-optic device operation where photorefractive damage can degrade performance.
What are the lattice constants and crystal structure of the ATOMFAIR Lithium Niobate substrate (5x5x0.5 mm, (0001))?
The crystal structure is trigonal with lattice constants a = b = 5.148 Å and c = 13.863 Å. These parameters are essential for epitaxial growth compatibility and phase-matching calculations in nonlinear optical applications.
This 5×5×0.5 mm (0001) single-side polished LiNbO3 substrate provides nonlinear optical grade material with broad transmission (0.4–2.90 μm) and high electro-optic coefficients, suitable for frequency conversion and electro-optic modulation, but requires careful handling due to its single-side finish and inherent photorefractive sensitivity.
Positive
- Broad transmission bandwidth: Spectral transmission from 0.4 to 2.90 μm covers visible and near-infrared, enabling use in parametric oscillators, frequency doubling, and acousto-optic devices across these wavelengths.
- High nonlinear and electro-optic coefficients: d33 = 34.45 pm/V and γ33 = 31 pm/V provide efficient second-harmonic generation and electro-optic modulation, reducing drive power requirements in device applications.
Trade-offs
- Single-side polished only: This substrate is supplied single-side polished, limiting applications that require double-sided optical access or symmetric surface quality for transmission geometries.
- Undoped photorefractive susceptibility: The material is undoped LiNbO3; MgO doping is noted as a method to improve optical damage threshold, implying higher power applications may risk photorefractive damage without additional doping or operational care.
