Abstract
The present disclosure relates to systems, methods, and computer readable media for modeling thermal effects within a multi-laser device. For example, systems described herein may include a plurality of laser devices that output energy streams having corresponding operating windows. One or more systems described herein may include a set of accumulators for tracking quantities of energy samples within operating windows and populating a queue representative of the tracked quantities. One or more systems described herein may additionally include filters and a summing module for determining temperature values for operating windows and synchronizing the temperature values with one another to determine an accurate system temperature for the multi-laser device. The features described herein facilitate synchronization of data for corresponding operating windows to provide an accurate determination of system temperature based on a combination of self-heating and crosstalk effects between multiple laser devices.
