Laser streaming: Turning a laser beam into a flow of liquid
WebThe device of a CO2 laser produces light when electricity runs through a gas-filled tube. Furthermore, mirrors are at the end of the tube. One of the mirrors is fully reflective and the other allows some light through it. The gas mixture is usually composed of carbon dioxide, hydrogen, nitrogen, and helium. A mode-locked laser is capable of emitting extremely short pulses on the order of tens of picoseconds down to less than 10 femtoseconds. These pulses will repeat at the round trip time, that is, the time that it takes light to complete one round trip between the mirrors comprising the resonator. Due to the Fourier limit (also known as energy-time uncertainty), a pulse of such short temporal length has a spectrum spread over a considerable bandwidth. Thus such a gain medium must … chittenango ny weather
