APE PulseSelect Pulse Picker

Reducing the repetition rate of mode-locked lasers with a pulse picker

APE

pulseSelect is an acousto-optical pulse picker, developed for the special demands of femtosecond laser technology. Pulse distortion is minimised by a low dispersive design and the use of reflective optics. High repetition rates and high contrast rates are achieved by using acousto-optical elements.

Features:

  • Reduction of the repetition rate of mode-locked lasers
  • fs or ps mode-locked lasers (eg, Ti:S)
  • Low dispersion design suitable for ultra-short pulses down to < 20 fs
  • Division ratio continuously variable between 2 260,000
  • Synchronised to laser seed with internal trigger
  • Single-shot up to 3 MHz with external TTL trigger
  • External trigger-gate mode

The Single pulseSelect consists of an optical module and control electronics. A Bragg cell represents the most important part of the optics, which selects individual pulses from the laser beam due to the acousto-optical effect. Focusing mirror, collimator mirror and a beam stop for the zero-order beam complete the setup. The driver electronics supplies the modulated RF signal for the Bragg cell with a carrier frequency that corresponds to the multiple of the laser repetition rate.

pulseSelect in a double configuration is available in two variants, Serial and Parallel. The Serial variant offers an improved contrast ratio of over 6000:1. The Parallel version allows the simultaneous picking of pulses from two synchronised laser sources.
