New lasing technique inspired by brightly colored birds

New lasing technique inspired by brightly colored birds: More recently however, optics researchers have found that another way to hold on to the light is to drill air holes in a material that causes the light to become trapped as it moves between the holes.
The air holes in the material can be placed either in a clear ordered fashion, producing just one strong wavelength, or in random fashion which allows for multiple wavelengths but isn’t very efficient; something that grows in importance as the laser power desired grows and uses more energy when it is produced.
The new technique falls somewhere in-between, in that at first glance the air holes appear to be random, but upon closer inspection, turn out to be ordered after all.
