The laser spectrum approximation by Voigt probability distribution allows inclusion of the essential contributions of the white phase noise and 1/f-phase noise simultaneously.
In order to determine the laser spectrum, first we need to know the autocorrelation function [[PHI].sub.EE]([tau]) of the signal E(t), which can be defined as
Proudly built in the United States, the new laser line offerings will push the boundaries of nanotechnology within the manufacturing sector, with more precise laser spectrum, higher strength, lighter weight, and increased control, allowing for more flexibility in an ever-changing environment.
