Final answer:
Class 1M lasers are safe under normal conditions but can be hazardous if magnifying optics are used. They have medical applications, including removing cancerous tissue. The intensity of these lasers can significantly exceed that of sunlight, posing risks to the eyes.
Step-by-step explanation:
The classification Class 1M refers to a type of laser that is generally safe under normal operating conditions, but may pose potential hazards if viewed with collecting optics, such as microscopes or telescopes. These lasers emit in the wavelength range from 302.5 nm to 4000 nm. The 'M' stands for 'Magnifying,' indicating the potential risks when used with magnifying optics. In medical applications, lasers like these might be employed for precise procedures, including the removal of cancerous tissues.
Calculating the intensity in W/m² of a medically applied laser involves understanding the amount of energy delivered to a specific area over a certain period of time. When it comes to the average intensity of sunlight and its comparison with a laser beam, such beams can greatly exceed the intensity of natural sunlight. This means extra caution is required, especially if such a beam were to accidentally enter the eye, as it could result in severe damage due to its high intensity and focused nature.
