Knowledge Assessment

Assess the knowledge you have acquired with this lesson

lasers enabling ultrafast machining

CO2, Nd:YAG and excimer lasers

picosecond and femtosecond lasers

nanosecond and microsecond lasers

improper laser wavelengths

thermal and mechanical workpiece damage O improper laser beam diameter

There are no limitations.

nearly all kinds of solid materials

only materials with low hardness

only heat-insensitive solid materials

It does not depend on the laser pulse length.

the shorter the laser pulses, the higher the ablation threshold

It is much lower compared to long pulse laser ablation.
