Thermal3 Command
ldd cal (dual|a|b) <setpoint>

Variables setpoint The setpoint power from 2.0 to 50.0 watts.

Description The "Calibrate" laser diode control mode will enable the laser power supplies, enable the beam-pointing, set the laser current(s) to 120% of the threshold current(s), detect the write laser using the beam-pointing, ramp the laser current to the estimated current, enable the laser power control loop and enable the calibrate power control loop. The calibrate power measured by the beam-balance sensor will be used to adjust the setpoint power for the laser power control loop. When both the laser power control loop and the calibrate power control loop settle to within 1% for 1 second, the write laser has settled.

Notes Thermal 1.0 / 1.7x equivalents:
  • The monitor command ldd cal (dual|a|b) <setpoint> is comparable to laser on.

Thermal 2 equivalents:
  • The monitor command ldd cal (dual|a|b) <setpoint> is comparable to ldd mode calibrate <setpoint>.
