Lasers have for long been used in aesthetic medicine. New laser clinics also keep popping up due to lax laws surrounding the use of laser machines. For instance, most doctors prefer Sentient Lasers for cosmetic purposes. They are useful for treating different types of skin conditions; these include wrinkle reduction, pigmentation, tattoo removal, acne, scars, and more. However, there are various things that you still need to know about lasers.
Here are things that you probably don’t know about lasers:
- Lasers come in distinct types& Classes
Although many lasers look similar, they are all different. They come in distinct characteristics and materials. Weak lasers are safe to the eyes and are categorized as class one lasers. On the other hand, the most powerful ones fall under class four and are strong enough to cause fires!
These machines also vary in output wavelength, average power, pulse rate, beam quality, and beam size. When shopping for laser equipment, understand the conversion efficiency and consumable requirements of the laser machine. The main types of lasers are;
- Solid-state laser.
- Gas laser.
- Liquid laser.
- Semiconductor laser.
- Einstein played a role in laser discovery!
Theodore Maiman designed the laser in 1960. But Einstein had a role to play in ls discovery. We now have lasers today, thanks to his theory of stimulated emission. He also contributed to many other types of technology that we use today, including GPS.
- Microwave Amplification by Stimulated Emission of Radiation was the first laser.
A MASER is comparable to a laser, but its light isn’t visible. The first one was constructed at Columbia University and was discovered by Townes Basov and Alexander Prokhorov. The two won another prize for the discovery in 1964.
- Laser lets you do everything!
Since the laser’s invention, many commercial, medical, and military applications have since come up. You can use medical lasers as scalps or even get rid of those unwanted tattoos. Lasers are also useful in cutting, welding, surveying, and communication companies globally.
Other incredible uses of laser technology are;
- Barcode readers
- LiDAR
- Optical tweezers
- Laser scalpel
- Laser cutters
- Fiber optics
- Optical storage
- Laser beams come in varying intensities.
Laser beams feature different intensities. This is mostly dependent on the amount of energy and the atoms involved in the stimulation process. This then defines the intensity of the photons emitted and the resultant laser light. More intense beams are less safe, and the beams are classified into four classes.
Four is the most intense, but class one lasers can’t generate dangerous electromagnetic radiation. Class one lasers are widely used for daily applications, while class two are relatively safe. But, they form visible beams and can lead to eye damage.
Final thoughts
Lasers play a crucial role in our everyday lives. They are used extensively in cosmetology, and you can find laser technology in many other products that you use daily. However, the laser scientific breakthrough isn’t a one-off event; the technology has evolved to become what it is today.
