Question 1/4

Which types of lasers are referred to as 'ultrafast' or 'ultrashort pulsed' lasers?

lasers enabling ultrafast machining

CO2, Nd:YAG and excimer lasers

picosecond and femtosecond lasers

nanosecond and microsecond lasers

Question 2/4

What are the limitations using 'conventional' lasers for precise micromachining?

improper laser wavelengths

thermal and mechanical workpiece damage O improper laser beam diameter

There are no limitations.

Question 3/4

Using ultrafast lasers enables precise processing of what kind of materials?

nearly all kinds of solid materials

only materials with low hardness

only heat-insensitive solid materials

Question 4/4

What about the ablation threshold using ultrafast lasers?

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.
