PPK: Synchro RF Driver for Fast Pulse Pickers

Description

These drivers have been designed in order to offer the highest possible performance in high speed Pulse Picking applications. They include a programmable built-in signal generator synchronised on the laser repetition rate. These systems are perfectly adapted to fibre pigtailed pulse pickers, but is equally suitable for use with AA’s range of free space devices.

Key Features:

  • High stability system with Pulse to Pulse Stability contribution <0.5% (PPKAc)
  • Dedicated to 80 MHz repetition rate lasers (PPKA) and lower (PPKS)
  • Input reference clock from Laser
  • With Built-in High accuracy signal generator
  • Including Digital delay and window gate adjustments
  • Consecutive pulse extinction ratio (CPER) optimisation
  • Bluetooth Remote control, USB, RS32 communication for set up
  • RoHS compliant

Pulse Picker Applications

  • To obtain high pulse energies in ultrashort pulses, it is frequently necessary to reduce the pulse repetition rate. This can be achieved by placing a pulse picker between the seed laser and the amplifier. The amplifier will then act only on the wanted pulses. The blocked pulses do not necessarily constitute a strong energy loss since the average power of the seed laser may be small compared with the average output power of the amplifier, and the remaining average power can
    be sufficient for saturating the amplifier.
  • In a cavity-dumped laser, a pulse picker (often called cavity dumper) extracts the circulating pulse from the cavity in only every Nth round trip. During all the other round trips, the pulse experiences low optical losses and can be amplified to a high energy.
  • A pulse picker can be used for injection and extraction of pulses in a regenerative amplifier
