Dear Dr. Robert,

We would like to congratulate you on the selection of your topic for the ERC Synergy Grant 2022. We also find your approach “ – ” fundamentally exciting and wonder if you plan to use ultrafast wide tunable lasers as well.

Our multiple award-winning laser system is precisely designed for science and has already enabled many papers. Our USP, besides the flexibility and the spectrum capabilities, is the high stability in terms of power, reproducibility and reliability. You can find a first overview here.

If this is interesting for you, we would like to hear about the possible application in a short video call to evaluate fairly and transparently whether our system can fit. Otherwise, if this is not of interest to you, we will not press you further on this.

We are looking forward to your feedback. Either way, we wish you and your Université Paris Dauphine – PSL much success.

Kind regards,

Ben

laser sharp random number generator

Caught the headline of Science News on a super-fast random number generator based on a dysfunctional laser! Producing “254 trillion random digits per second”.

“…when the laser is shined on a surface, its light contains a constantly changing pattern of tiny pinpricks that brighten and dim randomly. The brightness at each spot in the pattern over time can be translated by a computer into a random series of ones and zeros.”

I presume this is covered in the original Science paper [which I cannot access] but the parallel series of 0’s and 1’s should be checked to produce independent Bernoulli B(½) variates before being turned into a genuine random number generator.
