Required Equipment
CAUTION: The accuracy of the calibration depends completely upon the measurement of
laser pulse energy using a separate instrument as an independent calibration standard. If
the calibration standard is inaccurate or not used correctly, then the built-in energy meter
will also be inaccurate after calibration.
♦
An accurate, NIST-traceable, laser power meter for use as a calibration standard. The
selected calibration standard must be accurate for the appropriate wavelength and range
of pulse energies. The meter’s sensor element or input attenuator must withstand, without
damage, the range of fluence and peak power per unit area typical of the laser.

Calibration Procedures
There are three detectors in the system: 1) a resonator port that samples the full energy of the
beam prior to coupling into the optical fiber, 2) a calibration port that samples the full energy
leaving the handpiece, and, 3) the internal monitor for monitoring pulse-to-pulse stability of the
dye laser. All three detectors must be calibrated as part of a complete service calibration. These
calibration procedures are detailed in the following pages.
Before starting the calibration, however, verify that these preparatory steps are taken.
♦
Verify that the cal port window is clean.
WARNING: Failure to keep the cal port window clean may result in incorrect
calibration.
♦
Be sure that the fiber optic is properly routed and secured.
♦
Install a 7-mm handpiece.
