Some time ago, we described a procedure to manually create a look up table for the laser power slider to achieve linear power. Now, if you have a Thorlabs’ PM100D meter your job has been made much easier, as Scanbox can perform the calibration automatically. As a first step, you will need download and install the…

Pockels cell modulation via look-up tables
The Scanbox card keeps the laser power per pixel constant across the imaging field despite variations in dwell time during the resonant scanning cycle. It also blanks the laser entirely near the edges of each line. The shape of the modulation signal is fully programmable, although each change requires a firmware update to the board. We achieve…
