Principles of Lasers and Laser Safety
|
|
|
This two-day introductory level course is designed to give the participant with limited laser and optics background a solid introduction to lasers and safety concepts based upon ANSI Z136.1, FDA/CDRH, OSHA, and state requirements.
The course begins with a general overview of basic laser and optics concepts. The fundamentals of laser operation, laser terminology, and laser beam properties will be discussed, along with basic laser optics. Common types of lasers, including solid-state, gas, and diode lasers are described in this part of the course as well.
The student will then learn about the biological effects of laser radiation of various types and how this depends upon whether the laser is operated in CW, pulsed, or repetitively pulsed mode. Exposure limits are introduced including sample MPE, NHZ and OD calculations. The laser hazard classification concept is discussed, and an overview of laser accidents is presented.
The course concludes with a review of engineering, administrative and procedural controls needed for safe laser operation.
