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
