What effect does a materials surface have on the Laser beam?

To determine

The effect of material surface on the laser beam.

Explanation

All the materials reflect, absorb and transmit some fraction of light. The reflecting capacity of the material affects the efficiency of the laser operation.

As the temperature of the material increases due to partial absorption of the laser light, the absorptivity of the material increases and the reflectivity decreases. Because of increasing absorptivity the material starts of absorbs maximum radiation from laser and starts to heating up...
