          Electro-optic Pulse Picker

 

We have developed a complete line of Pulse Selection Systems for use with Ti:Sapphire, YAG, YLF and OPO’s from 350nm-to 1600nm applications. Customized options are also available.

 

Features:

·         Pulse selection: select from single pulse to 30MHz from mode locked lasers

·         Rep. Rate: Up to 30Mhz

·         Transmission: >85%

·         Pulse width: Min. pulse width of 18ns measured at zero

·         Pulse width limit: no limit

·         Rise/Fall time: 8ns

·         Offset: centre in and centre out operation. No office or angular change

·         Dispersion: no spatial dispersion.
