Pulsed Ti:Sapphire Laserwith multi-pass amplifi er

Our new pulsed Titan-Sapphire laser is based on the resonator concept of our reliable and well developed NarrowScan dye laser.

The combination of a 20-fold prism beam expander with a holographic grating in grazing incidence confi guration guarantees stable operation and excellent bandwidth over the whole tuning range without the use

of intracavity etalons.

A second and third Titan-Sapphire crystal are used as pre-amplifi er and 3-pass main amplifi er, allowing for high conversion effi ciencies even at

high pump energies.

The laser is build of our well known, high stable mirror mounts, together with our solid and very precise tuning device, which can be controlled

either by a control keyboard supplied with the laser or a PC.

* when pumped with an Innolas Yagmaster YM-R-1000 10 Hz ** depends on grating confi guration
