Peak output power as a function of injection current for a QCL with different AR coatings. The back facet of the device was HR coated. Inset: measured and predicted WPE as function of mirror losses for the same device.
cw output power, voltage, and WPE as functions of the current for a -long, thermoelectrically cooled, HR/AR coated QCL operating at room temperature.
Top: average output power as a function of the duty cycle of uncooled -long, HR/AR coated pulsed QCLs. Bottom: light-current-voltage characteristic of an uncooled cw QCL.
Dependence of WPE of chips with HR and optimized AR coatings on cavity length computed using Schindler’s method.
