Laser typesand uses

Health Canada published changes to the Radiation Emitting Devices Regulations (Laser Products) in Canada Gazette, Part II, on October 9, 2024. Learn more at: New requirements for laser products: Notice.

Handheld lasers and laser pointers are popular and widely available in Canada. Battery powered handheld lasers may resemble pens or flashlights. These are most commonly used to point at objects in lectures or presentations. However, they may also be advertised for other uses. A simple handheld laser pointer can be more than a million times brighter than the average 100-watt light bulb in your home.

How manytypesoflaser

"Laser" is an acronym that stands for "Light Amplification by Stimulated Emission of Radiation." A laser typically emits a very focused and intense beam that can travel long distances. Some laser products are safe, but others can be very dangerous and can lead to injury if safety measures are not taken.

Science geek note: the Fresnel lens was invented by a French physicist in the 1800s, and was originally used in lighthouses to concentrate the light beam. Several excellent examples can be seen at historic lighthouses, including several in Oregon.  When seen full size in a lighthouse, they are quite amazing!

The manufacturer of a laser product should also provide a user manual or instructions for safe assembly, maintenance and operation. The specific information that must accompany a laser product depends on the intended application and the hazard classification. Make sure to read the information carefully to understand the potential hazards and how to avoid them.

For more “well seasoned” climbers, reading the small print on a map or phone screen can be tricky. But who wants to bring reading glasses on a hike or climb?

Changes have been made to the Radiation Emitting Devices Regulations (laser products) concerning the scope of products and safety requirements for lasers that are imported, sold or leased in Canada. These changes were published in Canada Gazette, Part II, on October 9, 2024 and take effect 1 year after this date.

For these reasons, a controlled laser safety environment and professional laser safety training are necessary for the safe operation of Class 3B and 4 laser products.

Example of an alternative label, in English, appropriate for a Class 4 laser product. The label has a rectangular shape, with 5 panels bordered in black. The 4 panels on the top have a white background. Panel 1 shows the warning label. Panel 2 has an exclamation mark in a yellow triangle, the word DANGER on a red background, and the words LASER 4. Panel 3 has a red cross-out symbol and an eye that is exposed to a laser beam. Panel 4 has a red cross-out symbol and a hand that is exposed to a laser beam. Panel 5 has a yellow background and a black legend in the centre. The following words are in uppercase: AVOID EYE OR SKIN EXPOSURE TO DIRECT OR SCATTERED RADIATION

In-person instruction from a qualified instructor is strongly recommended for any technique that, if you do it wrong, could result in serious injury or death.

Health Canada administers the Radiation Emitting Devices Act (REDA) and its Regulations, which cover the sale, lease, advertisement, and importation of radiation emitting devices, including lasers. It's the responsibility of the manufacturer, importer or distributor to ensure their laser product complies with the applicable requirements set out in REDA and its regulations.

What are the 3typesof lasers

Under the International Electrotechnical Commission (IEC) Standard 60825-1, laser products are categorized in the following order, from the lowest to highest potential hazard: Class 1, 1C, 1M, 2, 2M, 3R, 3B and 4. Classifying lasers according to their hazard level helps determine the necessary control measures to reduce the risk of eye and skin injuries. These measures include engineering safety features that are built into the device, warning labels, and user information.

For example, Class 3B and 4 handheld portable lasers are considered a danger to human health or safety under the Canada Consumer Product Safety Act. Their sale, import, advertisement and manufacture are prohibited in Canada.

So, the way I heard the story . . . Several older and experienced hikers were hiking in the Columbia River Gorge. As light was fading, they needed to make a route choice at a trail junction. They pulled out their map . . . and couldn’t read it because no one had reading glasses! They didn’t know where to go, and decided to stay put for the night. (That was probably the best choice, and luckily they had the gear to do so in reasonable comfort.) The next morning, when there was enough light to read their map, they walked out unassisted.

Laser products categorized as Class 3R or lower can be operated safely if used as directed and should always be used with caution. Here are a few guidelines to reduce your risk.

The label may provide information about the emission duration (time between pulses) or tell the user if the laser beam is visible or invisible.

Even a quick look into the beam of any visible laser, at any classification, can result in temporary effects such as dazzle, flash blindness or afterimages. Looking into the beam of a Class 3R laser can cause serious damage to the eyes. An eye injury can also occur if someone looks at a Class 1M or 2M laser through a telescope, binoculars or a magnifying lens.
