Morning

Presentation – assessment of knowledge and needs

Theory:

• Principle of operation of a laser.
• The properties of the laser beam.
• Optical selectivity.
• Concept of ablation thresholds (minimum and maximum).
• The different effects brought into play during ablation, photomechanical effect, photothermal effect, photochemical effect.
• The different types of laser and their mode of operation (nature of the effect used).
• The notion of fluency.
• The NF EN NF 16782 standard for the use of a laser in restoration.
• Security:
  • Standards, recommendations, INRS.
  • Risks, means of protection, optics and smoke.
  • The organization of the site.
  • The job description.

Afternoon

Practical work :

• Preparation of the work area.
• Safety of the work area.
• Contextual design of the job description.
• Use of the laser on different supports in LQS mode and SFR mode.
• Application of standard NF EN 16782.

Theory:

Theoretical support during practical exercises.
