text: Yo, check it out, I got a story to tell
  'Bout a laser-based system, ARPES, that's swell
  Using photons at 6 eV, can't you see?
  From a mode-locked Ti:sapphire, it's the key
  
  This light source, it's a game-changer, no doubt
  Boosting momentum resolution, count rate, no clout
  Extrinsic background reduced, surface sensitivity too
  Compared to higher energy light, this system's true
  
  In this review, we break it down, no joke
  Describing the optical system, ain't no smoke
  Special experimental considerations, low-energy ARPES in sight
  We know the deal, we shine the light
  
  Calibration of the electron analyzer, we got it down
  For that low-energy angle-mode performance, we wear the crown
  And finally, we bring the heat, the Bi2212
  That high T(c) superconductor, we break it down, no one else can do
  
  Comparing the data, see how it flows
  To the results from higher photon energies, that's how it goes
  So there you have it, the story's complete
  ARPES system, revolutionizing the beat
