44 lectures in English for PhD, MSc students and postdocs. 23 lecturers who are specialists from all over the world gave these lectures with animated powerpoint supports and videos. Our podcast deals with various aspects of parametric nonlinear optics: classical and quantum pictures, geometries, materials, devices and applications. The 45 lectures were recorded during the first International School on Parametric Non Linear Optics (ISPNLO). It was organized By Pr Benoit Boulanger, Pr Robert W. Boyd and Pr Patricia Segonds. ISPNLO took place at Les Houches in France from 25th April to 1rst May 2016. The housing being limited, only 59 students had the chance to attend this school and live with the lecturers during 15 days. This school was labelled as an event of the International Year of Light 2015 (IYL 2015), and it was a thematic school of Centre National de la Recherche Scientifique (CNRS).It was sponsored by IYL 2015, CNRS, Société Française d’Optique (SFO)
Great lecture, By the who else can see a dog's face on green board the behind professor. Writing has been cleaned in the way using a duster that formed an image.
Hi i have found an error in 18:00 to 19:00 you tell about solving the equations but d(S)/dt is not equal to Gamma S but maybe equals to S^(dagger), can you help me with this?
video presentation, is not comfortable, barbecue the laser pointer is not visible (i know technically the content is different screen than actual screen with laser pointer)
Wow, very useful. Unfortunately i get here by very specific coincidents so no doubts its have a not such much views. But i hope owners of this channel not running to idea "get more views", because as part of world wide community agreement of transfering knowlege and information to all people independently of their wealth its absolutely beautiful and perfect. Thanks for teaching me something new, Paul Corkum
P2 (the induced second order polarization) is proportional to chi-2 and the square of the electric field. The electric field we are considering is that from the laser source, which is E1.
@ 4:36 We only see that two laser beams are converted by a crystal in four laser beams. Without the crystal it does not happen. So scattering is not demonstrated here ... "in front of your eyes".
i read his book before knowing about this lecture, and i always imagined him as such a lovely humble person who is also fun and talks about this subject with joy, and i wasnt wrong. we are so honored for his personality
did you read the entire book? i mean thoroughly.? difficult for me to read after some pages.. because the background knowledge needed is lacking in me. i suppose.
19:19 Can femto lasers be turned into laser weapons? Can the laser actually be one squared centimeter, at least in principle? Companies like Honeywell, Lockheed Martin, Raytheon, Northrop Grumman, and Boeing promote 1mw lasers. The HHG pulse "probe" generates 8 orders of magnitude more power.
One thing that occurred to me when watching this is that the resolution of the image is independent of how far away the detector is from the object, in the configuration where the object is illuminated with the patterns. Of course, you might need a telescope or other optical devices to increase the signal to noise ratio at the detector. I'm not sure where that setup with a close projector, but a distant detector would be helpful, but who knows.
all entangled pairs are correlated. The point he wanted to emphasize is that you just need photons with correlation. Creating entangled pairs is an easy way to know for sure that your photons are correlated.
Entangled photons are correlated, but correlated photons are not necessarily entangled. Entangled means that there is some quantum connection between the photons, like photons that are generated in the same nonlinear crystal. Correlated means that there is a known relation between the photons. Parallel beams of light from two laser pointers are correlated, but not entangled, because if you measure one beam, you know the state of the other beam.
