Pumped Medium A pumped medium, also known as a laser gain medium, is the active material within a laser system that undergoes optical pumping to produce laser light. Pumped mediums can include gases (such as CO2), liquids (such as dye solutions), or solid-state materials (such as crystals or semiconductors) that exhibit specific optical properties conducive to laser emission.
In laser engraving, the pumped medium absorbs energy from the pump source and undergoes stimulated emission, generating coherent laser light that is directed onto the material surface for engraving or marking. The choice of pumped medium depends on factors such as desired laser wavelength, power output, and application requirements in laser engraving processes. |
