Measuring laser coherence with modified interferometer
Researchers designed a modified Mach-Zehnder interferometer to measure the spatial coherence of a double-cavity laser across its entire beam profile simultaneously. This robust, portable setup enables coherence analysis without movable parts. Results showed complex coherence patterns that changed with pulse energy, guiding optimal use of the laser for interferometry.
