Internal modulation

The modulator is introduced into the cavity and changes its parameters.

Power Management:

For technological purposes, the laser power density is controlled using a conventional lens system.

1 - collimator;

2 - working lens.

The formation of the hole in depth is due to the evaporation of the material. Depth of field is the deflection of the focal plane.

The physical process of interaction of the laser beam with the material.

1) Heating of the material as a result of which the mobility of the electrons of the lattice increases.

2) Melting (for welding, cutting, drilling).

3) Secondary electron emission.

4) Thermonuclear reaction.

The angular divergence depends on its mode structure.

The more transverse modes, the greater the divergence.
