Pulse Picker

Accessory for Selecting Pulses from Modelocked Ti:Sapphire Oscillators

The acousto-optic Bragg cell in the head provides simple single-pass diffraction of the pulse train, while the controller lets the user select any repetition-rate by dividing the Ti:Sapphire oscillator frequency by any integer from 4 to 4096. By applying external control signals, rates down to even single shot are possible.

Two Bragg cell options are available, SiO₂ for applications demanding the highest contrast ratio for input powers >2W, or the TeO₂ cell which is recommended for input powers <2W and for higher diffraction efficiency.

• For use with femtosecond or picosecond lasers
• Wavelength options covering 500 to 3000 nm
• Single-pass Bragg cell for easy alignment
• High diffraction efficiency and contrast ratio
• Dedicated controller with CPU
• LCD display of operational parameters
• Controller settings provide widely variable repetition-rate: 9.5 kHz to 4.75 MHz
