Abstract :
GaInNAs-based 1240 nm laser diodes are realized with internal losses as low as 0.5 cm-1 allowing maximum output powers of 9 W at room temperature under continuous-wave operation. Wavelength stabilized tapered laser diodes show output powers of 1W and M2 down to 1.4 demonstrating potential for pumping applications.
