SmartXide2 corrects skin imperfections and counteracts the effects of aging, such as wrinkles and flabbiness, by exerting a unique action on the tissues with effective stimulation of neocollagenesis. It is also ideal for areas hitherto considered untreatable such as the The SmartXide2 unique features and power allows for the creation of fractional laser pulses with variable durations and peak powers, something completely new in CO2 laser technology.
The 55 Watt Lasersonic laser is used in several surgical specialties. The CO2 Laser is used with a handpiece, surgical laparoscope or with attachments for an operating microscope. Many minimally invasive intra-abdominal procedures and microscopic surgical approaches benefit from this technology.

CO 2 Lasers have been available in medicine since the early s and have been used in dentistry for more than 25 years. They are a 10, nm infrared wavelength, which is highly absorbed by water. Articulated arms or hollow waveguides are used to transmit CO 2 laser beams and quartz optical fibers cannot be used. The CO 2 gas is in a chamber with nitrogen and helium and the active medium is pumped with an electrical current.
CO 2 lasers are very efficient and exhibit excellent hemostasis. The traditional 10, nm CO 2 lasers are currently for soft tissue uses only. They are continuous wave lasers that can be operated in gated wave modes, including what are termed "superpulsed" modes.
It is important to note that even the superpulsed mode is not a free running pulsed mode. These superpulsed gated modes offer improved surgical control with less charring of tissue. CO 2 lasers are excellent tools for incising tissue for multiple purposes. Incisional and excisional biopsies, frenectomy, gingivectomy, pre prosthetic procedures, and the like are all achieved with excellent hemostasis.
Sutures are rarely needed and the controlled thermal effects and sealing of nerve endings often makes for a very comfortable post-operative experience for the patient.
This wavelength is also very effective for ablation and vaporization of leukoplakia and dysplasia. A hard tissue capable CO 2 laser has become available recently. This laser's CO 2 molecule uses an oxygen isotope that crates a beam at nm. This particular wavelength has a high absorption affinity for hydroxyapatite that allows for efficient vaporization of tooth structure.
Its water absorption is much lower than Erbium lasers so hydroxyapatite absorption and vaporization predominates when cutting enamel, dentin, and bone. Hard tissue ablation with the nm CO 2 laser is a photothermal event, not photoacoustic.
As a result much higher temperatures are generated and much higher pulse rates are needed to cut. You did not finish creating your certificate. Failure to complete ALL the steps will result in a loss of this test score, and you will not receive credit for this course.

The carbon dioxide laser CO 2 laser was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in ,  and is still one of the most useful types of laser. Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. The CO 2 laser produces a beam of infrared light with the principal wavelength bands centering on 9. The specific proportions vary according to the particular laser. Because nitrogen is a homonuclear molecule , it cannot lose this energy by photon emission, and its excited vibrational modes are therefore metastable and relatively long-lived. The CO 2 then radiatively emits at either

co2 laser physics pdf
CO2 Lasers: Effects and Applications examines and summarizes the important applications of the device in different areas of study like physics, chemistry, and engineering. In some parts of the book, the reader is assumed to be knowledgeable in university level mathematics or some specialized area in physics or chemistry. The book consists of 10 chapters where the first two establish the general concepts on lasers and CO2 lasers, respectively.
Chemical treatment methods are most often used nowadays for polymer surface modification; however, new technologies are now considered, especially in physical treatment methods, as laser technologies. Infra-red lasers, like CO 2 , appear to be advantageous due to their large beam size, high efficiency, easy operation, use of non-toxic gases and low cost.

Даже если Беккер успеет спуститься вниз, ему все равно некуда бежать: Халохот выстрелит ему в спину, когда он будет пересекать Апельсиновый сад. Халохот переместился ближе к центру, чтобы двигаться быстрее, чувствуя, что уже настигает жертву: всякий раз, пробегая мимо очередного проема, он видел ее тень. Вниз.
Поэтому такая перспектива даже не обсуждалась. Сьюзан старалась сохранять самообладание. Мысли ее по-прежнему возвращались к сотруднику лаборатории систем безопасности, распластавшемуся на генераторах.
Хейл побледнел. - Что это. - Стратмор только сделал вид, что звонил по телефону. Глаза Хейла расширились. Слова Сьюзан словно парализовали его, но через минуту он возобновил попытки высвободиться.
