Arbitrary laser frequency modulation algorithm based on iterative on-the-fly deconvolution

Year: 2025

Type: article

Abstract: I present a general laser modulation control algorithm. I implement the LIDAR frequency modulated continuous wave (FMCW) scheme as a special case of study. My proposal applies to any arbitrary modulation pattern and is based on an iterative algorithm that infers the laser transfer function in order to perform on-the-fly deconvolution. I present an experimental proof-of-principle using an external-cavity diode laser, the accuracy of which I analyze by comparing the obtained frequency response with a targeted modulation pattern. In addition to the FMCW scheme, I am also testing square wave modulations, which are more demanding in terms of bandwidth.
