Nd:YAG diffusion-bonded composite laser crystal slabs – LOT OF 9

Product Description

Lot of 9 Diffusion-Bonded Composite Nd:YAG Laser Crystal Slabs – US Defense Lab Surplus

Acquire a rare surplus lot of 9 high-performance, diffusion-bonded composite Nd:YAG laser crystal slabs from a U.S. Defense Laboratory’s advanced imaging laser radar program. These custom-fabricated slabs were designed for demanding photon-counting ladar applications requiring exceptional gain, thermal stability, and compact high-power operation.

🔬 Key Specifications:

• Material: Diffusion-bonded composite Nd:YAG with undoped YAG end caps

• Doping: 1.9 at.% Nd in the central gain section (high doping for strong absorption and high gain in short lengths)

• End Caps: ~1 mm thick undoped YAG on each end (reduces thermal lensing and parasitic oscillations)

• Geometry: Slab format (rectangular cross-section) – superior for heat dissipation and power scaling

• Approximate Dimensions: ~6 mm length × ~2 mm × ~3 mm cross-section (assorted sizes in lot)

• Appearance: Central pink-tinted doped section flanked by clear undoped caps – classic composite signature

• Manufacturer: Northrop Grumman SYNOPTICS (defense-grade composite specialist)

• Condition: Excellent – Unused/New Old Stock appearance, carefully stored in original Gel-Pak anti-static carrier (included)

🎯 Applications & Uses:

These premium gain media are designed for 1064 nm operation (with harmonics at 532 nm, 355 nm, etc.) and are ideal for:

• Diode-pumped slab lasers

• High-peak-power Q-switched or mode-locked systems

• Master oscillator power amplifiers (MOPA)

• Coherent/photon-counting ladar & 3D imaging

• Scientific research, materials processing, medical lasers, and spectroscopy
