Fiber laser arrangement and method for generating high-power laser radiation |
| abstract |
In a fiber laser arrangement with a doped active fiber, laser radiation from a seed laser at a wavelength above the spectral gain maximum of the active fiber is amplified by optical pumping in the active fiber. The fiber laser arrangement has a pump laser arrangement for optically pumping the active fiber with first pump radiation of a first pump wavelength and a device for generating second pump radiation of a second pump wavelength, which lies between the first pump wavelength and the wavelength of the seed laser. The doping concentration and length of the active fiber as well as the power of the first pump radiation are coordinated in such a way that the active fiber absorbs >90% of the first pump radiation in the first fiber section, radiation of the second pump wavelength in the first fiber section by the first pump radiation to generate the second pump radiation and the laser radiation of the seed laser are then amplified in the remaining second fiber section by the second pump radiation. This enables efficient amplification of long wavelengths, for example at wavelengths > 2070 nm in a Tm-doped active fiber with better efficiency than in a Ho fiber amplifier. |
