Abstract:
A reflectance detection method in which a workpiece is irradiated with a laser beam and reflectance is detected, irradiating, with a light amount H0, the workpiece with a laser beam with a first wavelength X1 shorter than a detection-target wavelength X and detecting a light amount H1 of reflected return light, irradiating the workpiece with a laser beam with a second wavelength X2 longer than the detection-target wavelength X with the light amount H0 and detecting a light amount H2 of reflected return light, and employing H calculated based on an expression shown below as the light amount of return light obtained when the workpiece is irradiated with the detection-target wavelength X and calculating reflectance obtained when the workpiece is irradiated with the detection-target wavelength X based on H/H0. H=H 1+( H 2− H 1)×( X−X 1)/( X 2− X 1)

Claim (Index 2):
A reflectance detection method in which a workpiece is irradiated with a laser beam and reflectance is detected, the reflectance detection method comprising:\n a reflectance calculation step of causing a laser beam having a first wavelength X1 shorter than a detection-target wavelength X regarding which reflectance is desired to be detected and a laser beam having a second wavelength X2 longer than the detection-target wavelength X to coalesce by a coupler to irradiate the workpiece with a resulting laser beam with a light amount H0, and detecting a light amount H of reflected return light to calculate reflectance obtained when the workpiece is irradiated with a laser beam having the detection-target wavelength X based on H/H0, wherein if output power that generates the light amount H0 of the irradiation of the workpiece is defined as W0, output power of the laser beam having the first wavelength X1 is defined as W1, and output power of the laser beam having the second wavelength X2 is defined as W2, the output power of the laser beams when the irradiation is carried out in the reflectance calculation step is set based on an expression shown below,\n W 1= W 0\u00d7( X 2\u2212 X )/( X 2\u2212 X 1) \n W 2= W 0\u00d7( X\u2212X 1)/( X 2\u2212 X 1).
