Broadly tunable mid-infrared intracavity difference-frequency laser.
We generated diffraction-limited laser radiation that is continuously tunable from 3.1 to 4.4 microm by mixing the output from a Ti:sapphire laser with the intracavity field of a single-frequency, 1.064-microm Nd:YAG ring laser. A peak output power of 300 microW was observed near 3.2 microm at a Ti:sapphire input power of 300 mW.
