The LPC is a precision instrument for measuring, modulating, and stabilizing laser beam powers. In one system it does the work of a power meter, a variable attenuator, and a laser intensity stabilizer. Long term (8 hours) stability is typically 0.03% (rms)


Long Term Stability 0.03%
Transmittance >85%
Noise Reduction 1Hz 200:1
Power Display Accuracy 5%
Bandwidth up to 5khz Aperture 4mm
Rs232. GPIB or Front panel control

LPC options
  • RD40 VIS/NIR (425-1100nm) remote detector
  • RD40-UV  (325-1100nm) detector for doubled/tripled beams
  • RD40-IR   (950-1700nm) remote detector
  • LPC-GPIB GPIB computer interface
  • LPC-CBL-EXT Extended length cables
  • LPC-VIO Voltage input option



With a 2MHz noise reduction bandwidth, this hybrid stabilizer uses a Liquid Crystal (LC) cell and Pockels cell feedback elements. This allows us to provide a high frequency noise reduction without the HIGH VOLTAGE drive requirements of typical Pockels cell stabilizers.

For those in need in UV stabilization down to 325nm we have been selling our LS-101 model as a semi-custom system. Based on the CRi LS-100 model, the LS-101 is a Pockel cell based stabilizer which is available by special order. Please contact us for details.

For those operating in the UV by using a doubled or tripled fundamental beam the LPC in conjunction with a RD-40-UV can provide excellent stabilization.
