Six amazing things to do with lasers

Lasers are in the news as usual, this time inspiring a list of what Lewis Carroll’s White Queen might have characterized as "six impossible things” to be believed before breakfast. But thanks to optics and photonics, these things are all possible with the help of lasers:
(1) Removing layers of pollution from centuries-old decorative plasters as well as marble and bronze statues.
Laser techniques development supported by the TEMART and CHARISMA projects at the Istituto di Fisica Applicata ‘Nello Carrara’ – Consiglio Nazionale delle Ricerche (IFAC-CNR) have enabled restoration of such masterpieces as Donatello's Profet Abacuc, the Etruscan masterpiece Arringatore from the Trasimene Lake, wall paintings such as the painting of the Santa Maria della Scala museum complex in Siena and the catacombs of Rome, and the Florence Baptistery's North Door, a gilded-brass masterpiece by Lorenzo Ghiberti.
(2) Getting clear,detailed pictures of distant objects in space.

Feeling the pinch of sequester? Take the survey, have your say



You know that scientific conferences are not junkets and that cutting national investments in technology R&D will cut national competitiveness in the global market. We hear it from every segment of photonics, and heard it particularly loud and clear at SPIE Defense, Security, and Sensing in Baltimore recently.
Now you have a new chance to join with others in getting the message out.
A survey has been opened to gather input from the scientific community about the impacts of the sequester. We are passing along the invitation from Benjamin Corb, Director of Public Affairs at the American Society for Biochemistry and Molecular Biology, for you to take part and provide the photonics perspective in this cross-disciplinary effort.
Ben says:
"As science advocates continue to advocate for increases in federal investments in research – and against the sequester – we constantly hearfrom our meetings the need for stories and data on impacts of sequester.  In an effort to collect the da…
