US 10,837,828 B2 · Non-attenuating meter for determining optical energy of laser light

Abstract

A non-attenuating meter determines optical energy of laser light in an absence of optical attenuation of the laser light and includes: a recipient mirror that: receives laser light that propagates in a primary propagation direction; produces profile light; transmits the profile light through the recipient mirror along the primary propagation direction; produces first reflected light from the laser light; and reflects the first reflected light along a secondary propagation direction; a profilometer in optical communication with the recipient mirror and that: receives the profile light from the recipient mirror along the primary propagation direction; and produces a profile signal from the profile light; a sensor mirror in optical communication with the recipient mirror and a passer mirror and that: receives the first reflected light from the recipient mirror along the secondary propagation direction; produces, in a tertiary direction, a sensor force from the first reflected light; communicates the sensor force to a force sensor along the tertiary direction; produces a second reflected light from the first reflected light; and reflects the second reflected light in a tertiary propagation direction; the passer mirror in optical communication with the sensor mirror and that: receives, along the tertiary propagation direction, the second reflected light from the sensor mirror; produces pass light from the second reflected light; and reflects the pass light along the primary propagation direction, such that the non-attenuating meter does not attenuate the optical energy of the laser light and does not change the primary propagation direction of the laser light.
