- Light Amplification by Stimulated Emission of Radiation
Associated hazards:
1.Laser Beam: eye injury, burns, skin cancer (UV), fire hazard
2.Active medium: toxic chemicals or gases (organic dyes, BeO in Ar lasers, HF, HeCd, HeHg, HeSe)
3.Excitation source: high voltage, water cooling
اسلاید 2 :
- laser beam can be focused by cornea and the lens to a very tight spot on the retina
اسلاید 3 :
Eye Injury
اسلاید 4 :

اسلاید 5 :
Skin Burns
- CO2 laser reflected from a metal surface
اسلاید 6 :
Types of laser eye exposure
اسلاید 7 :
Laser hazard classes
- Classification by wavelength and output power, according to their ability to produce damage
اسلاید 8 :
Safety measures
- Be informed
- Eyewear for classes IIIb, IV for everybody in the room
- Beam paths above >200 mW should be guided through tubes
- Highest risk during alignment, optical setup modification
اسلاید 9 :
IIIb and IV requirements
- EHS 280 Laser Safety Training
- EHS 281 Laser Safety Retraining (every 3 years)
