The perfect laser does not exist. There will always be a bit of phase noise because the laser light frequency moves back and forth a little. Phase noise prevents the laser from producing light waves with the perfect steadiness that is otherwise a cha
Ultra-precise lasers find their use in various applications. For example, power cable monitoring, quantum computers, optical atomic clocks, and much more. However, all lasers tend to make noise, which scientists from DTU Fotonik wish to reduce with the help of machine learning.
