> tia sal2 The magnetic field and electric field together make up the laser's optical radiation, so a photodiode and a DVM can measure the magnetic field quite accurately. Both fields alternate in direction at roughly 500 THz for a red laser, so low-frequency measurement magnetic measurement techniques aren't too useful. Cheers, Phil Hobbs | |||||||||||||
