What are the main characteristics of the ruby laser used in medicine?
Best insight from top research papers
The ruby laser utilized in medicine exhibits key features that make it highly effective for various applications. It is known for its high energy density, directivity, and coherence, making it valuable in medical procedures like tattoo removal and treating skin issues. Typically, medical ruby laser systems have a maximum repetition rate of 2Hz and an optical output beam energy of 1J. To enhance operational efficiency, efforts have been made to develop new ruby laser power systems with higher repetition rates, such as 4Hz, achieved through dual cavities. Additionally, the use of a diode-pumped solid-state laser with a ruby crystal gain medium and a high-bandgap semiconductor pump source enables direct optical pumping, resulting in laser output at a wavelength of around 694 nm.

What are the uses of lasers in dentistry?5 answersLasers in dentistry have a wide range of uses. They are used in routine dentistry for various treatments such as periodontics, implantology, orthodontics, and restorative dentistry. They can be used on both soft tissues and hard tissues including bone, enamel, and dentin. In restorative dentistry, lasers can cause cracks in the teeth and affect composite restorations. Lasers are also used in the diagnosis and treatment of tooth decay, gum disease, biopsy or lesion removal, teeth whitening, and other procedures. They are preferred by patients due to their ability to cause less pain, require less anesthesia, and reduce anxiety. Lasers have shown tremendous results in dentistry and are used as a replacement for conventional approaches such as scalpels and blades. They have advanced the field of dentistry by providing more advanced and modern tools for dental care. Lasers offer superior results over traditional methods and have applications in pediatric dentistry as well.
What are the effects of laser therapy on surgical wounds? animal?5 answersLaser therapy has been studied for its effects on surgical wounds in animals. One study found that low-level laser therapy (LLLT) did not appear to influence the healing of primarily closed incisions and full thickness open wounds in dogs. However, another study showed that LLLT was effective in the treatment of sutured and open wounds in animals, with better results seen with specific laser parameters. Additionally, a study on diabetic rats with skin wounds found that LLLT was effective in decreasing oxidative stress levels in surgical wounds. These findings suggest that the effects of laser therapy on surgical wounds in animals may vary depending on the specific parameters used and the type of wound being treated.
How is laser beneficial in medicine especially in lasik surgery?3 answersLaser therapy in medicine, including LASIK surgery, offers several benefits. In LASIK surgery, the use of femtosecond-assisted laser technology has shown advantages over conventional techniques. It allows for the creation of a thin-hinged corneal flap without using a blade, resulting in more predictable corneal flaps, better visual acuity, and fewer chances of developing dry eyes. Additionally, lasers have revolutionized various medical fields by providing less invasive treatment options. They have been used in general surgery, ophthalmology, dermatology, and other specialties to cut, coagulate, and remove tissue, resulting in better wound healing outcomes. Laser therapy has also been effective in lithotripsy, cancer treatment, cosmetic procedures, and the ablation of abnormal conductive pathways. However, it is important to note that lasers can cause tissue damage and scarring, which can be minimized by understanding laser mechanisms and adjusting parameters. Overall, lasers offer significant advantages in medicine, providing precise and effective treatment options with minimal invasiveness and improved outcomes.
What are the different applications of photonic energy in medicine?4 answersPhotonics-based techniques have various applications in medicine. They are used for functional clinical diagnosis, progress monitoring in treatment, and metrological control. In cardiovascular medicine, photonics technology is used for intracoronary imaging and sensing, laser ablation, and optical pacing. Photonics is also applied in the delivery of bioactive agents, such as drugs and photosensitizers, to increase efficiency, reduce side-effects, and control dose, place, and time of delivery. In pain research, photonics technologies are used to monitor neuronal activity and study pain relay circuits. These applications of photonic energy in medicine provide new insights and capabilities for diagnosis, treatment, and understanding of various diseases and conditions.
What are the advantages and disadvantages of different wavelengths of laser weapons?3 answersDifferent wavelengths of laser weapons have their own advantages and disadvantages. The best laser is the one that the practitioner can use best. Laser weapons using optical radiation have the advantages of unlimited, weightless ammunition, a huge range, almost instantaneous delivery of energy, silence, and self-targeting under certain circumstances. Laser weapons are effective at long or short distances due to their unique characteristics such as narrow bandwidth, high brightness, coherence in time and space, and the ability to travel at the speed of light. The wavelength of the laser determines its effects on body tissues, defining the clinical role of each laser. Different lasers, such as the carbon dioxide laser, the argon laser, the neodymium: YAG laser, and the tunable dye laser, have specific applications based on their wavelength and tissue absorption properties. Laser weapons emit radiant energy that may pose potential hazards to the eye and skin, and their classification is based on output power and ability to cause harm.
