New Pockels Cells for fastest switching >1.3 MHz -Image

The new LINOS Double BBO High-Repetition Pockels Cells (DBBPC HR) from Qioptiq feature two crystals in an optical series to enable the fastest possible switching rates available today with >1.3 MHz performance.

This Pockels Cell is made especially for fast Q-switching as required in regenerative amplifiers or for pulse pickers. Due to its low absorption, BBO is the crystal material of choice for high average laser powers.

Conventional BBO Pockels cells suffer from piezo ringing at high switching rates (several hundred kilo Hertz) which generates so much heat that  performance degrades and the Pockels cell can be damaged. Superior thermal relaxation of the DBBPC HR design eliminates any requirement for additional cooling and also allows fast tuning of the switching rates.

The DBBPC HR Pockels Cell is available with extra-long crystals and small apertures which reduce the switching voltage even further. Thus the driving electronics are less complex and permit half-wave voltage applications where required.

In addition to our high damage threshold coatings for 1064nm and 1030nm, customer-specific wavelengths are also available upon request.

Standard specifications:

  • Apertures:  ø2.7mm or ø3.2mm
  • Wavelength: 1030nm
  • Transmittance: ≥ 98%
  • Extinction ratio (without voltage): >1000:1
  • λ/4 voltage @ 1030nm (± 10%; DC): 1.4kV (ø2.7) or 2.0kV (ø3.2)
  • Capacitance: < 8pF
  • Damage Threshold: > 4 J/cm2
