In this paper, we propose an optical surface measurement based on laser scattering to monitor situ the laser cleaning threshold for the removal of graffiti. This technique is meant to assist the laser removal process using laser pulses of 10 ns at 1064 nm while probing the weak laser beam at 632 nm. The diagnostic apparatus consists of a HeNe laser performing a probing light source and...

Oral presentaion

This paper presents a development of an optical arrangement that captures photons traveling in the multi-pass fashion based on a so-called laser recirculation. An optical trapping scheme is relied on the principle of nonlinear frequency conversion. In this demonstration, a L-shape resonator performing as the master cavity provides a laser beam with a fundamental frequency to create the...
