"..The results show that the frequency producing the greatest stress relief occurs at the resonant frequency (natural frequency). The reduction of residual stress after resonant vibratory treatment can attain 97%. Sub-resonant VSR treatments get less or no residual stress relief, depending on the frequency level applied."
This process saves a great amount of heat energy to do the same stress relief using just vibration. This gives an indication of small amounts of energy applied in a resonant fashion has a notable heat energy equivalence - irregardless of the heat loss from the furnace.

Most people are familiar with the popular laser pointing devices. Laser light is unique in that it is a powerful beam of 'coherent' light. Coherent light means vibrating light with the same momentum, frequency, and phase. This type of light is 'triggered' in a material by an escalating light 'bouncing' back and forth between mirrored ends in an energized material. It is simply a photonic version of people doing 'the wave' in a stadium. Energized electrons in an atom are triggered into emitting a 'photon' of light as 'the wave' comes through. It is synchronized light - or coherent light.
