VueMetrix has expanded its Vue series compact laser diode controllers with the Vue-HC line, which includes 45- and 90-A CW and 50- and 100-A quasi-CW devices. All combine the driver and diode mount in a 3 X 4 X 6-in. package. Accompanying software has built-in standard and advanced functions, such as constant power and constant current modes, and diode current limits. A mouse click generates and plots an LIV curve. Multiple controllers can be connected to a single computer, creating a benchtop burn-in system for wafer characterization and packaging research and development. A driver board integrates them into a laser system's power supply and control electronics. Temperature regulators, photocell inputs and a microprocessor are embedded.
