Universal discriminant for continuous-wave operation of laserdiodes

摘要

We propose a simple and powerful criterion for definingncontinuous-wave (CW) operation of laser diodes. Our criterion isnrepresented by a quasi-triangular region in the plain spanned byndimensionless parameters Α and Β. These parameters, deducednfrom the characteristics of the laser diode operating under pulsedncurrent injection, represent the effects of the turn-on voltage and thenseries resistance on the increase in the CW threshold. We demonstratenthe validity of our criterion using blue-green lasers made from II-VInsemiconductors as examples
