Red Optronics LBO crystals 3x3x5mm

Product Description

Lot of 3 Red Optronics LBO Nonlinear Crystals – 3×3×5 mm, θ=90° φ=0°, Sealed New/Old Stock

This is a rare, matched lot of three Lithium Triborate (LiB₃O₅, LBO) nonlinear optical crystals manufactured by Red Optronics. Each crystal is identically specified: 3×3×5 mm with orientation θ=90°, φ=0° for Type I non-critical phase matching (NCPM). The entire set remains sealed in its original protective plastic container, ensuring pristine, contamination-free condition. These crystals are engineered for efficient, walk-off-free frequency conversion in demanding laser applications.

Key Specifications (Per Crystal):

• Dimensions: 3 × 3 × 5 mm

• Orientation: θ = 90°, φ = 0° (XY plane, Type I NCPM)

• Phase Matching: Non-critical (NCPM) – zero walk-off, wide acceptance angle

• Ends: Polished, uncoated

• Transparency Range: 160–2600 nm

• Damage Threshold: >10 GW/cm² @ 1064 nm (nanosecond pulses)

• Condition: New/old stock, unused – sealed together in original container

Why This Lot Is Exceptional:

• Matched Set from Same Batch: Ideal for multi-stage experiments, spares, or comparative testing.

• Sealed Integrity: Original packaging ensures no handling damage or surface contamination.

• High-Performance LBO: Superior to KTP/BBO in damage threshold and thermal properties for many high-power applications.

Primary Application:

Second Harmonic Generation (SHG) of 1064 nm to 532 nm (green) with temperature tuning (~140–150°C). Also suitable for third harmonic generation, sum/difference frequency mixing, and optical parametric oscillation/amplification (OPO/OPA).

Applications:

• Green Laser Systems: Intracavity or extracavity frequency doubling of Nd:YAG, Nd:YVO₄, or Nd:YLF lasers.

• Nonlinear Optics Research: Prototyping for OPO/OPA, wavelength conversion, or ultrafast laser systems.

• High-Power Laser Development: Where LBO’s high damage threshold and thermal stability are critical.

• Educational Labs: Teaching nonlinear optics, phase matching, and frequency conversion principles.
