Description:
We generated a coherently synthesized optical pulse from two independent mode-locked femtosecond lasers, providing a route to extend the coherent bandwidth available for ultrafast science. The two separate lasers (one centered at 760 nanometers wavelength, the other at 810 nanometers) are tightly synchronized and phase-locked. Coherence between the two lasers is demonstrated via spectral interferometry and second-order field cross-correlation. Measurements reveal a coherently synthesized pulse that has a temporally narrower second-order autocorrelation width and that exhibits a larger amplitude than the individual laser outputs. This work represents a new and flexible approach to the synthesis of coherent light.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shelton, R K -- Ma, L S -- Kapteyn, H C -- Murnane, M M -- Hall, J L -- Ye, J -- New York, N.Y. -- Science. 2001 Aug 17;293(5533):1286-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉JILA (formerly Joint Institute for Laboratory Astrophysics), National Institute of Standards and Technology (NIST) and University of Colorado, Department of Physics, University of Colorado, Boulder, CO 80309-0440, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11509721" target="_blank"〉PubMed〈/a〉
