Experimental characterization of filamentation phenomena in pressure-mounted diode laser bars

Laser diodes are important to our modern society and have many interesting appli- cations. They however still have some aspects to be studied, to improve their performance and reliability. In this work, the emission of two diode laser bars, each with different configurations and from different manuf...
