IPC: G01B11/08
Filed: 1994-12-29
Abstract: PURPOSE: To enhance accuracy in the measurement of beam diameter by measuring the variation rate of laser output when a wire traverses the cross-section of beam and the variation of traverse mode and then comparing the measurements with calculated values. CONSTITUTION: A metal wire is traversed across the cross-section of a laser beam in a resonator and the variation rate of laser output and the variation of traverse mode are measured sequentially at the positions on the beam cross- section corresponding to the wire position when the wire traverses the cross-section of beam. The measurements are then compared with the values calculated according to formulas I, II and II thus determining the conditions for substantially matching the measurements with the calculated values within a range where the traverse mode of oscillating laser is sustaining the TEMoo mode. Finally, the diameter of laser beam is determined at the passing position of wire on the cross-section of beam based on the conditions thus determined.  In the formulas, I(x) is power stored in the resonator, Io is the initial value of power, α(x) is the loss of the wire, R is the reflectance of reflection film, G is an amplification factor, ω0 is the radius of laser beam, α0 is the loss in the resonator except the wire loss.
