BNA Organic Crystal
• THz/MIR generator and detector
• Multi-THz generator
• Second harmonic generator
We use our IP-protected Sapphire-BNA technology to overcome the damage of BNA crystals from high power Ti:Sa 800 nm lasers.
Examples of Sapphire strongly helps in preventing the heating up and melting of the BNA crystal. 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).
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.
OPA 1250 nm: > 6 MV/cm (pp). Super broad spectrum. 0.8% efficiency. Perfect beam profile. Diffraction limited focusing using our RIGI microbolometer camera.
DSTMS operates with all conventional types of lasers
• Ti:Sa 800 nm
• OPA/ OPCPA
• 1030 nm laser
• Input laser: 1 mJ Ti:Sa 800 nm
• Output THz: 1 MV/cm, 2.1 µJ
Application 1: Intense Nonlinear Spectroscopy
Comparison with conventional ZnTe sources:
Application 2: Broadband Linear Spectroscopy
Comparison with conventional Lithium Niobate sources:
Application 3: X-ray Streaking Camera
BNA spectrum provides 5 times better streaking resolution than Lithium Niobate presently employed in all X-ray streaking cameras.
