My skimming of the articles indicates the efforts with lasers are not simply as a source of optical pumping light, but the FMing seems to be aimed at a kind of limited trapping of the Rb atoms to improve performance.
My original question was simply can the discharge lamp be replaced with a SS (LASER ?) light source to get rid of lamp life issues. I don't know what the BW of the excitation source has to be, but I'd expect that any light outside a narrow bandwith is wasted, or maybe even degrades S/N. -John ============== > Hi Paul, > > From: "paul swed" <[email protected]> > >> Well I would be curious what on earth a VCEL laser diode costs.
