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 help 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).

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. 


OPA 1250 nm: > 6 MV/cm (pp). Super broad spectrum. 0.8% efficiency. Perfect beam profile. Diffraction limited focusing using our RIGI microbolometer camera.

Laser Requirements

DSTMS operates with all conventional types of lasers​

      • Ti:Sa 800 nm 

      • OPA/ OPCPA

      • 1030 nm laser

Expected Output

•  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.
