Laser diode with a frequency converter |
March 11, 2008 |
| A semiconductor laser diode that internally converts one or more short wavelength "pump" beams to an output beam at a longer wavelength using nonlinear optical frequency conversion in the semiconductor. Modal phase matching of the pump and output beams in a semiconductor waveguide allows |

Laser diode with an amplification section that has a varying index of refraction |
September 11, 2007 |
| A high powered laser diode that includes a pumped stripe section with a varying index of refraction. The varying index of refraction can reduce the self-focusing phenomenon found in high powered laser diodes in the prior art, thereby providing a high quality output beam. The index of |

Laser diode with a spatially varying electrostatic field frequency converter |
March 8, 2005 |
| A semiconductor diode laser that generates light at wavelengths longer than conventional diode lasers. The laser includes a first gain element that generates a first "pump" laser beam having a first frequency and a second gain element that generates a second "pump" laser beam having a se |
