A luminescence pulse has been observed from a laser-created bubble in liquid nitrogen and liquid argon at the first collapse point of the bubble. An unusual feature is that the width of the pulse is of order 100-1000 ns, much longer than the 2-8 ns pulses observed when the same experiment is carried out with a water sample.
