6 Notable Scienti�cAccomplishments

With Lasers

Since its inception, the laser has been integrated into all facets of science, health, and technology, bringing these industries to great new heights. Let’s take a look at some of the most notable things lasers have accomplished in the realm of science.

LASER

CANCER TREATMENT

Carbon dioxide lasers can be applied to some precancerous cells and skin cancers.

Argon lasers can be used in conjunction with a special photosensitive drug to kill cancer cells.

Nd:YAG lasers can, with help from optical �bers, access hard-to-reach parts of the body, allowing for the treatment of throat cancers.

Laser-induced interstitial thermotherapy (LITT) is used to heat areas of the body near tumors and cancerous cells to shrink or damage them.

The types of lasers used in cancer treatments include:

EYE SURGERYLASIK surgery has become one of the most common laser

applications in modern medicine. The procedure aims to correct vision problems, including:

The procedure works by physically reshaping your cornea so that light focuses on your retina properly.

Myopia(nearsightedness)

Hyperopia(farsightedness)

Astigmatism

INDUSTRIAL APPLICATIONS

You don’t have to worry about sharpening, maintaining, or replacing tool bits as lasers don’t use any contact tools.

Brittle, pliable materials that are di�cult to process with conventional hand tools are easy to manipulate with lasers.

Lasers are easily automated, allowing you to reinvest manpower in other areas of production.

The laser o�ers signi�cant advantages over hand tools and machines in commercial and industrial applications.

THESE ADVANTAGES MAKE LASERS PERFECT FOR

DENTAL PROCEDURES

Tooth decayLasers can remove decayed tissue inside your tooth and prepare the enamel for �llings.

Lesion removalLasers can relieve pain from canker sores and other lesions in the mouth.

Gum diseaseLasers can remove bacteria and reshape your gums to prevent gum disease.

WhiteningAfter applying a peroxide bleaching solution, a dentist can speed up the whitening process using a laser.

BiopsyUsing a laser, a medical professional can take a small piece of gum tissue to be examined for cancerous cells.

Lasers have been put to great use in dentistry for:

COSMETIC SURGERYThe laser’s precision makes it perfect for cosmetic surgeries. Lasers can help remove sunspots, tattoos, and hair. Cold laser therapy is an e�ective, noninvasive alternative to liposuction to contour the body.

Sunspots

Hair

Tattoos

PAIN RELIEFLow level laser therapy uses low wavelengths of light to accelerate healing and relieve pain for a variety of acute and chronic conditions, particularly neck and back pain.

The laser is placed over the injured area. The photons penetrate up to 5 centimeters below the skin, passing through to the subcutaneous tissue.

Photosensitive elements in the cells absorb and interact with the light.

Absorbing the light, the cells trigger processes that heal damaged tissue, increase intracellular metabolism and reduce pain, edema, and in�ammation.

It’s amazing to think that the laser—a beam of concentrated light—has become so integral to our everyday lives, but it has certainly made things easier and promises great developments as laser technology continues to grow.

Let There Be Light!
