INTRACAVITY FREQUENCY-CONVERTED SOLID-STATE LASER FOR THE VISIBLE WAVELENGTH REGION |
摘要 |
The present invention provides an intracavity frequency-converted solid state laser for the visible wavelength region. The laser comprises a semiconductor laser (1) with an extended laser cavity (2). A second laser cavity (4) is formed inside of said extended laser cavity (2). The second laser cavity (4) comprises a gain medium (3) absorbing radiation of the semiconductor laser (1) and emitting radiation at a higher wavelength in the visible wavelength region. The frequency converting gain medium (3) is formed of a rare-earth doped solid state host material. The proposed laser can be manufactured in a highly integrated manner for generating radiation in the visible wavelength region, for example in the green, red or blue wavelength region. |
