We have been awarded an early career grant from the Department of Energy, Basic Energy Sciences. A writeup by the University appears here: http://sb.cc.stonybrook.edu/news/general/2016-05-04-thomas-allison.php  

Our first paper has now been published, and can be found here: http://dx.doi.org/10.1364/OPTICA.3.000311

Our first group member, Melanie Reber, has accepted an assistant professor position at University of Georgia in Athens, GA. There, she will start her own research group pursuing  ultrafast optical spectroscopy of gas-phase molecular systems. Congratulations to Melanie!

After a nearly three year period building unique instrumentation, our first paper is submitted. The paper is available on the arXiv pre-print server here: http://arxiv.org/abs/1511.02973

We have recently added an enhancement cavity to the pump beam of our cavity-enhanced spectroscopy experiment, allowing us to excite the molecules about 100x more and realizing the full potential of CETAS.

After a long build, high harmonics are being generated. Without much optimization yet, we are recording about 40 nA of photocurrent from a stainless steel plate and the signal goes away upon insertion of a LiF window, meaning the photon … Continue reading →

We have now assembled the last part of the beamline connecting the surface science chamber to the HHG source. Pictures are graduate students Peng Zhao and Xinlong Li and postdoc Chris Corder. Now, just add photons…. coming soon!

Today we installed the chamber for our time preserving monochromator. The beamline is taking form!
