| Description | We have developed improved methods for complete characterization of the space-time fields of ultrashort optical pulses with complex spectra across a broad range of wavelengths. These are being applied to a novel source based on multiple phase-locked disjoint spectra. |
| Exploitation Route | Continued discussion with companies for potential licensing opportunities. In particular conversations with APE GmbH, who have licensed related prior technology and currently manufacture instruments based on this. Collaboration with other institutional partners with an interest in determining what pulses they have generated. In particular, a collaboration with the group of Prof. Derryck Reid at Herriot-Watt University, who is synthesizing attosecond optical pulses using several coherent light sources based on multiwave mixing. |
