Coherent energy migration in solids: Determination of the average coherence length in one‐dimensional systems using tunable dye lasers [PDF]
, 1976 The coherent nature of energy propagation in solids at low temperatures was established from the time resolved response of the crystal to short optical pulses obtained from a dye laser (pumped by a nitrogen gas laser).
