Answer

A laser emitting in the UV (wavelength < 400 nm) has a  lower  photon energy than a laser emitting in the IR (wavelength >1000 nm).

Answer

To melt or just heat a material, the preferred lasers are lasers emitting continuously (or emitting long-pulses) and preferably at wavelengths in the infrared (IR).

Answer

To minimize side effects while removing ("ablating") material, the shortest possible pulses should be preferred.

Answer

The refractive index describes how much light is absorbed in the material as the light propagates inside it.

Answer

During femtosecond laser ablation, there is no heat accumulation near the laser spot.
