| 摘要 |
The invention relates to a device for generating light pulses. The device comprises a seed laser source (1) for generating input light pulses. An optical pre-amplifier (2, 3) having variable gain receives the input light pulses from the seed laser source (1). An optical power amplifier (4, 5) receives the light pulses from the optical pre-amplifier (2, 3) and amplifies and compresses the received light pulses. The light pulses are compressed in the optical power amplifier (4, 5) in such a manner that the pulse duration of the output light pulses of the optical power amplifier (4, 5) is tunable via adjusting the gain of the optical pre-amplifier (2, 3). Wavelength-tunable light pulses are obtained by supplying the output light pulses of the optical power amplifier (4,5) to a highly non-linear optical fiber (6). |
