BNA Organic Crystal

N-benzyl-2-methyl-4-nitroaniline

BNA generates and detects across the terahertz and the mid-infrared. It runs on Ti:Sa 800 nm, on OPA / OPCPA, and on 1030 nm lasers. Our IP-protected Sapphire-BNA technology prevents the crystal from heating and melting under high-power Ti:Sa 800 nm pumping. Pumped by a 1250 nm OPA it delivers > 6 MV/cm (pp) at 0.8 % efficiency.

Applications — We use our IP-protected Sapphire-BNA technology to overcome the damage of BNA crystals from high-power Ti:Sa 800 nm lasers.

Sapphire strongly helps in preventing the heating up and melting of the BNA crystal. The images below are thermal images, 2 kHz / 800 nm. Sapphire-BNA was exposed to 12 mJ/cm², Glass-BNA was exposed to 3.7 mJ/cm². Work done by A. Gopal (Jena Uni, Germany). Idea from Johannes Hasse (PSI, Switzerland).

Example output, Ti:Sa 800 nm — > 4 MV/cm (pp). Smooth electric field trace. Perfect beam profile. Using old technology (no sapphire). Result by A. Gopal (Jena, Germany). Accepted to Opt. Express.

Example output, OPA 1250 nm — > 6 MV/cm (pp). Super broad spectrum. 0.8 % efficiency. Perfect beam profile. Diffraction limited focusing, measured with our RIGI microbolometer camera.
