  1. Just discovered this podcast, and chose “Lasers” to evaluate it it (since it’s something I know a little about) – Very entertaining show, but a couple of things stood out: How lasers work, with no mention of “meta-stable states”, or, “population inversion” – really?
    And laser guide stars have nothing to do with moisture in the atmosphere – the laser passes up through the atmosphere and ionizes a layer of sodium atoms in the upper atmosphere, which then shines like a star. By watching how that dances around you can tell what the atmosphere is doing to the laser beam and compensate your telescope accordingly.

  2. I’m surprised you missed the Astronomical Masers, which act primarily in the radio regime (i.e. between 1 GHz – 100 GHz). There have been several known: OH, water, SiO molecules etc.
