Dec. 2011: First group measurements of HHG

We have generated and detected high harmonics for the first time on the new atto beamline.
Harmonics 1: High harmonics (15-23). Focus is well before the gas target, resulting in a large divergence.Harmonics 1: High harmonics (15-23). Focus is well before the gas target, resulting in a large divergence.
Harmonics 2: High harmonics (15-23). Focus is near or after the gas target, resulting in a small divergence.Harmonics 2: High harmonics (15-23). Focus is near or after the gas target, resulting in a small divergence.

Dec. 2011: Polarization-encoded storage in Raman memory

We have recently demonstrated the storage of polarization-encoded information in the Raman memory with up to 97% Fidelity. If you are interested, please take a look at the paper on the ArXiv: http://arxiv.org/abs/1112.0900

Nov. 2011: Publication: Accuracy measurements in multishearing SPIDER

Article published: "Accuracy measurements and improvement for complete characterization of optical pulses from nonlinear processes via multiple spectral-shearing interferometry" in Optics Express.
SPIDER accuracy measurements: Tests of SPIDER accuracy by performing measurements with different sized spectral shears. A larger (smaller) shear improves (worsens) the precision, but reduces (increases) the spectral resolution. Combining all shears combines the best of both.SPIDER accuracy measurements: Tests of SPIDER accuracy by performing measurements with different sized spectral shears.
