Switch-less operation of a TEA CO2 laser.
We report here the operation of a UV pre-ionised mini-TEA CO2 laser where the use of an external switch has been dispensed with. This was rendered possible by making the preioniser spark array play a dual role- that of a switch as well as of a source of UV photons that pre-conditioned the inter-electrode volume.
متن کاملRotational Relaxation Studies in Co2 Molecules by Means of a Multiline Tea Co2 Laser System
One of the most serious problems in high-power, short-pulse, 10.6#m CO2 laser systems is the efficiency. When the short-pulse (pulse duration _~ 1 ns) amplification efficiency is compared to the efficiency of normal "long-pulse" (pulse duration "-lOOns) CO2 amplifying systems, the former is rather poor. As is well-known, energy extraction from a laser amplifier only occurs at the wavelengths wh...
متن کاملTreatment of Lymphangioma Circumscriptum with CO2 Laser: A case report
Lymphangioma circumscriptum is a congenital lymphatic malformation that results in gradual dilatation of lymphatic vessels and development of lymphatic cisterns. The treatment of choice is radical surgery. Other treatment methods including cryotherapy, sclerosing agent injections, radiation therapy and CO2 laser were suggested. We report successful treatment of a 14-year-old boy affected with l...
متن کاملautomatic mode switch (ams) causes less synchronization
conclusions switching ams off may increase biventricular pacing in some patients. case presentation in this case series, we present a combination of far field sensing and automatic mode switching (ams) in six patients. it is found that this combination causes ventricular sensing (vs) episodes with wide qrs and no synchronization. we turn off the ams and alleviate the problem. introduction cardi...
متن کاملTreatment of Rhinophyma with CO2 Laser
Rhinophyma is a benign and disfiguring tumor of the nose, affecting white old men. It represents the end stage of acne rosacea. Hypertrophy of the sebaceous apparatus and fibrosis lead to an enlarged, erythematous nasal tip with comedones. Treatment modalities include Isotretinoin (Which is not effective on severe rhinophyma), freehand scalpel shave, cryosurgery, electrocautery, dermabras...
