(a) 100 – 200 nm

(b) 200 – 500 nm

(c) 600 – 700 nm

(d) 800 – 900 nm

I have been asked this question during an online interview.

This is a very interesting question from Laser Beam Machining-Introduction in portion Thermal Processes of Advanced Machining

Answer 1

Correct answer is (b) 200 – 500 nm

To explain I would say: The wavelengths of Excimer laser used in LBM range from 200 – 500 nm.
