Otherwise accessing the wavelength correction Settings Corrections menus would be impossible Procedure Step 1 Set up your energy detector to measure the energy of your pulsed laser If you are working at a wavelength other than the calibrated wavelength first make the proper correction by following the procedures given in Section 2 3 3 1 Wavelength Setting Make sure that the energy level is below the detector s damage threshold and your laser still has good stability Step 2 Apply energy for a few minutes to warm up the detector This will reduce any thermal bias Step 3 Measure the energy level without the attenuator To reduce random uncertainty you should average a number of shots We recommend at least one hundred shots This should reduce random errors by a factor of 10 square root of N assuming a Gaussian distribution Step 4 Install the attenuator Without changing the laser settings measure the energy level by averaging the same number of shots All laser settings must be the same as Step 3 including beam size and position on the detector Appendix A Step 5 Repeat the first measurement Step 3 to make sure that nothing has changed during the procedure that would invalidate the calibration A change larger than the uncertainty of your measurements means that something in the laser or environment has changed You can either add this to your uncertainty when you use the attenuator or try to stabilize the
