Description

Our new carefully designed and optimized single mode ring resonator guarantees – in any configuration - high performance, stability and easy operation. All optical elements, including the dye jet and titanium:sapphire are mounted on an extremely rigid 58 mm diameter Invar rod. This extremely rigid, high thermal mass structure reduces system sensitivity to vibration and temperature changes.

In our laser system we adopted the concept of Coherent and improved some important features like handling, adjustability and costumer-friendliness. Our laser is characterized by very high stable, precise opto mechanical components and stable reproducability of the adjustment. Due to the fact that we use a hysteresis free Galvo drive instead of piezo drives, the laser is able to perform reproducable, narrowband wavelength scans.
