A standalone accessory for selecting pulses from femtosecond or picosecond Ti:Sapphire oscillators, featuring a rugged optomechanical head assembly and a versatile controller.
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.
