BBO Pockels Cells

BBO Pockels Cells

BBO pockels cells (BaB2O4), also known as barium borate pockels cells. They are a pockels cells device with superior overall performance. They feature high damage threshold, low insertion loss, high extinction ratio, minimal piezoelectric ringing and competitive price.

Furthermore, they exhibit significant advantages in laser power handling capability, and temperature stability, and are largely unaffected by piezoelectric ringing.

BBO pockels cells have significant advantages in the following areas:

  • High repetition rate Q-switches
  • Pulse pickup up to 3 MHz
  • Laser cavity dumping
  • Egenerative amplifier control, and beam choppers

BBO pockels cells are a better choice than the KDP pockels cells in a high repetition rate and high power applications. They have low voltage electrical coupling factor of the BBO. They can generate pulses with a repetition frequency of several hundred kilohertz.

Features of BBO pockels cells:

  • Low absorption and noise
  • High UV transmittance
  • High repeatability and damage resistance
  • Pockels Cells with double crystal design available
