Micro-transfer printing technology is rapidly emerging as an effective pathway for large-scale heterogeneous materials integration. Laser Micro Transfer Printing (LMTP) is a laser-driven non-contact variant of the process that makes it independent of the receiving substrate's properties, geometry, and preparation. In this paper, an opto-thermo-mechanical model is developed to understand the laser optical absorption and thermally-induced strains around the ink-stamp interface during the LMTP process. The model will be used in planning the process parameters (laser pulse duration, stand-off distance), estimating the ink-stamp temperature rise during the LMTP process, and understanding the LMTP process capabilities and delamination mechanism. Further, experimental observations are used to calibrate the model and verify its predictions.
