LightGate BBO Pockels Cells

Key Features

  • High Repetition Rate
  • Low Acoustic Noise
  • Damage Resistant Ceramic Apertures
  • High Average Power Applications
  • Compact design
  • Suitable for Q-switch and Regen-amp Applications
  • Lower Voltage Requirements Than Other BBO Cells


LightGate BBO Pockels cells are the preferred alternative to KD*P Pockels cells for high-average power and high repetition rate applications. The LightGate series BBO Pockels cell employs dual crystal geometry to minimize drive voltage (~3.4kV quarter-wave voltage @ 1064nm for 4mm aperture LightGate 4). BBO is transparent from approximately 0.2 to 2.1µm and is not subject to tracking degradation. It also shows low piezoelectric ringing, which is useful for repetition rates of hundreds of kilohertz.

LightGate Pockels cells are useful for regenerative amplifiers and as q-switches in high pulse repetition rate micro-machining lasers and high-average power lasers for material processing and metal annealing. G&H also offers special single long crystal cells, reduced voltage multi-crystal cells and cells that are attenuated for ultra-low ringing, for special applications.
