What Are Lasers Used for? 10 Surprising at-Home Uses for Lasers

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 … Web26 nov. 2024 · In fiber lasers, the laser source is silica glass mixed with a rare-earth element.
