Laser

The benefits of Laser based energy are:

  1. collimated monochromatic wavefront propagation allows narrow beam cross-section area for energy confinement over large ranges. [citation needed]
  2. compact size of solid state lasers-photovoltaics allows ease of integration into products with small form factors. [citation needed]
  3. ability to control radio-frequency interference to existing communication devices i.e. wi-fi and cell phones. [citation needed]
  4. control of Wireless Energy Access, instead of omnidirectional transfer where there can be no authentication before transfer. [citation needed]

These allow laser-based Wireless Energy Transfer concept to compete with RF or inductive methods. [citation needed]


The Laser "powerbeaming" technology has been mostly explored in military weapons (in Directed-energy_weapons[1] [2]) and aerospace Laser_propulsion [3] [4] applications and is now being developed for commercial low-power applications. [citation needed] Wireless energy transfer system using laser for consumer space has to meet critical Laser safety requirements standardized under IEC 60825. [citation needed]


The wiki Laser page has "Laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low-divergence beam". Is this a sufficient source for point # 1.
