Abstract :
The output power of an external-cavity-tuned laser has been significantly increased by using an output coupler with a wavelength-dependent reflectivity. Our algorithm for determining the optimum wavelength dependence uses a simple gain model, and all necessary parameters can be determined from measurements of the same actual gain medium that will be used in the tunable laser source. This approach also increases tuning range
