Laser safety regulations

Date & Time: May 1st 2012 (2:00 PM - 3:00 PM, 4:30PM - 5:30 PM)
Course level: Introductory
Instructor: Prof. Maria L. Calvo, Universidad Complutense de Madrid, Spain

Since the discovery of laser in 1960 the dramatic development of laser sources has provided  important advances in research and techniques in which laser equipments are key tools. Nowadays, laser sources are ubiquitous and used in many fields and areas from commerce, industry, biomedicine, material science, information processing to give some clear examples. However, lasers emit hazardous radiation and, therefore, its use requires the knowledge and applications of current protocols and standard universal classification of laser types. In the lecture we will revise all these aspects in order to assure a later safe use of the required lasers for any application purposes.

Laser safety theory and practice

Date & Time: May 1st 2012 (3:00 PM - 4:00 PM and May 2nd 2012 (9:00AM - 12:30 PM)
Course level: Intermediate
Instructor: Prof. Luis Diego Marin, Universidad de Costa Rica, Costa Rica

In this experimental course, the participants convert the essential theoretical contents on “Laser Safety”, into practice from an engineering point of view. The applications and use of the basics in calculations defined within the standards IEC 60825 or ANSI Z136, are summarized and trained by means of practical examples regarding:

  • Maximum permissible radiation for skin and eyes,
  • Minimum safety distance from a radiations source for direct and indirect irradiance of the skin and eyes,
  • Demonstration on damaging effect of laser radiation and characterization of pulsed laser systems.

These experiments create sensitivity for the dangers of laser use.
