Neodymium: Yttrium Aluminum Garnet - Nd:YAG SYNOPTICS manufactures Nd:YAG for use in industrial, medical, military and scientific applications. YAG is grown utilizing the Czochralski technique. The as-grown crystals are then processed into laser rods or slabs, coated in house and inspected per customer specifications. SYNOPTICS’ high volume capacity and complete capabilities for growth, fabrication, polishing, and coating makes us the clear choice as your Nd:YAG rod supplier. Advantages Of Nd:YAG Include: High gain Low threshold High efficiency Low loss at 1.06 µm Good thermal conductivity and thermal shock characteristics Mechanical strength High optical quality Material characteristics that allow for various modes of operation (CW, pulsed, Q-switched, mode locked, and cavity dumped) Standard Rod Specifications 0.6 – 1.3 ± 0.1 at % > λ / 4 per inch of rod length (λ = 632 nm) standard > λ / 16 per inch of rod length Opto-Lase 25 dB minimum Nd Concentrations Available Wavefront Distortion Extinction Ratio Dimensional / Mechanical Specifications Diameter Tolerance Length Tolerance Rod End Polished Flatness End Face Parallelism End Face Perpendicularity Chamfer Surface Quality Barrel Finish Standard Coating (High & Partially Reflective coatings available on request) +.000” / -.002” +.040” / -.000” λ / 10 within 10 arc seconds within 5 arc minutes 0.005” ± 0.003” x 45˚ 10 - 5 scratch-dig per MIL-O-1 3830A 55 ± 5 microinches (other finishes available on request) Anti-Reflection where R < 0.25% Durability per MIL-C-48497 Damage threshold exceeds 10 J / cm2
