Frequency doubled semiconductor laser having heat spreader on shg crystal |
| abstract |
A hybrid laser hybrid laser comprises a semiconductor laser (50) supported directly or indirectly on a package substrate (20), a frequency- doubling crystal (60) supported via a first surface thereof on a supporting surface of a thermally conductive support (40) connected to the package substrate, with the crystal positioned so as to be able to receive light from the laser, and a thermally conductive heat spreader element (80) mounted on a second surface of the crystal. The thermally conductive element has a thermal conductivity greater than a thermal conductivity of the crystal, desirably at least 100W/mK or even 300W/mK. The thermally conductive element is not connected to the package substrate or to the thermally conductive support. While the thermally conductive element or "heat spreader" does not act directly to cool the crystal by conducting heat away, it acts to increase the uniformity of the temperature of the crystal, allowing the crystal to achieve higher light conversion efficiencies while remaining within the constraints of the folded-path hybrid laser package. The preferred simple slab structure of the thermally conductive element allows for a very easily manufactured laser package and structure. |
