Beam diagnostics

It is essential with ultra-high power laser systems to accurately diagnose the laser pulse in order to optimise performance.  At the Central Laser Facility we have developed a number of diagnostics to measure, in particular, the laser beam quality and the laser pulse duration.

Beam profiling

• radial shear interferometer
• The 4-channel Laser Beam Profiler (4-LBP) is capable of acquiring up to four laser beam images simultaneously. Each detector is compact and can be triggered synchronously or independently. Operation over Ethernet allows laser beam monitoring to be carried out remotely in a client-server configuration.
  Powerful analytical techniques (image processing, beam centroiding, line profiles, FWHM, intensity integration, etc) enable beam measurements to be made.

Applications of the LBP include :

• monitoring a distributed laser system - multiple beamline data acquisition for small or medium sized systems (four channels or less)
• monitoring laser beams within a hazardous or clean room environment or anywhere where access is either restricted or under strict control.
• single shot laser beam quality measurement (M²)

Ultra short pulse measurement

• autocorrelator
