A new method to carefully restrict the power delivered to specific areas within a laser could lead to improvements in the laser’s output by many orders of magnitude.
A research team at Princeton University used mathematical calculations and computer simulations to test their theory that by limiting power delivery to a laser, the physical space in the laser absorbs the light rather than producing light. The optimal efficient portion of the laser shines far more brightly than previous estimates. This new development could lead to more sensitive and energy-efficient lasers, and increased control over frequency and spatial pattern of light emissions.
