Paper Abstract

Second-harmonic generation frequency-resolved optical gating (SHG FROG) is one of the most commonly chosen setups for pulsed light measurement and is characterized by a high sensitivity and robustness1,3 . In this article, a new implementation for a compact and portable LEGO SHG FROG setup is presented with the goal of measuring light pulses from an 800 nm laser at different experimental stages for diagnostic and validation of results in the VOXEL laboratory, at IPFN. With a “plug and play” cased setup, complete with LEGO two-axis tilters, holders and an overall assembled structure we hope to achieve a compact solution for a fast pulse characterization and easy mobility in between different laser stages. This low-cost customizable solution also aims to encourage academic institutions to introduce LEGO elements to multiple photonics experiments for an economical and viable approach.
