Different wavelengths affect performance based on material properties. A 445nm (blue) laser diode generally cuts and engraves wood more efficiently than an 808nm (infrared) diode due to better absorption by organic materials. The 445nm laser also allows for a finer focus, leading to more detailed work.

A 3-watt diode can cut hardwood, but slowly and shallowly, usually no more than a few millimeters deep. A 5-watt diode would cut faster and deeper, offering improved performance, but the difference may not be drastic.

For the Algolaser Alpha MK2, ensure proper heat dissipation and focus adjustment to optimize cutting performance.
