Laser engraver is a sophisticated setup involving different optical components. In the engraving process smoke is released and residuals are left. These residuals may be trapped in the engraver machine. A routine cleaning and maintenance are very crucial to keep it in optimized condition.
If we are working with the materials like foam or leather in which a lot of smoke and gas is released, the optical components may suffer and we may require regular cleaning. Laser engraving involves burn off and there is always a risk that hot residuals can damage the optical components. Therefore, continuous care and protection of machine is key for its long life.
Considering all this, the MOPA fiber lasers may be the ideal candidate for laser engraving. They provide higher output power and a better control of temporal pulse shaping, useful for laser engraving. They help in reducing the issues of burning, heat development, foaming etc. What’s more, unlike lamp-pumped solid-state lasers, the pump source, laser crystal, etc. of MOPA laser source do not need to be replaced regularly.
