Ultrafast & CW Ti:Sapphire lasers workshop in San Diego, CA

how often do you have to clean your optics? the dust is everywhere!

@Bacilla During educational workshops with many people around there is more dust that in a clean lab. But it's even better since attendees can see the laser beam better:) And during educational workshop we also show how to clean optics, so it's done in this case every day. In the clean lab, when laser is closed, the cleaning is required only once in a while, probably twice a year or even less.
