Fundamental Study of Catastrophic Optical Damage Mechanism for High Power Quantum Cascade Lasers
Abstract
A systematic study on catastrophic optical damage (COD) for high power quantum cascade lasers (QCL) is proposed. One of the main goals set for the program is the development and validation of a COD model capable of describing instantaneous laser damage at high optical power levels. The model will be used to fully define required changes to laser design and laser fabrication for reliable QCL operation at multi watt optical power level. Laser lifetime will also be studied in this program by observing the formation and propagation of various types of defects in the vicinity of the front laser facet during long term operation. The final goal for this task will be the development of a model predicting laser lifetime and the formulation of an accelerated aging process.
