We propose a laser optical device as a transducer for an adaptive control system to ensure uniformity and reproducibility of laser material processing procedures. We present and discuss some experimental results using optical fringes generated by a laser. We suggest combining PulsESPI, ESPI and acoustic detection measurements monitoring the 45°-bending-mirror external to the cavity as suggested by Emeritus Professor Dr. William Steen.
