Abstract
A laser arrangement for time-of-flight measurements includes an optical filter adjacent to a laser. The laser and optical filter each have a substrate and an active layer arranged between a first and second mirror. The laser emits laser light in a first direction through its first mirror. The optical filter receives the laser light reflected from an object through its first mirror. The laser's and the optical filter's first mirrors have an equal reflectivity. The laser's and the optical filter's second mirrors have an equal reflectivity, or the reflectivity of the optical filter's second mirror is reduced with respect to that of the laser. The optical filter filters the received light such that laser light reflected from the object and received from the first direction passes the optical filter.
