Laser chaos

To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced quantum chaos.
High-powered semiconductor lasers are used in materials processing, biomedical imaging and industrial research, but the emitted light they produce is affected by optical filaments; light structures that move randomly and change with time, causing chaos and making the light making it incoherent.
Now a research team led by Imperial College London have used quantum wave chaos in the cavity used to create the laser, so the laser itself remains steady. The study published in Science.
