BACKGROUND Tumors of the skin and subcutaneous tissue are the largest group of canine neoplasms. Total excision is still the most effective method for treatment of these skin tumors. For its universal properties the carbon dioxide (CO2) laser appears to be an excellent surgical instrument in veterinary surgery. Laser techniques are alternatives to traditional methods for the surgical management...

Fractional continuous wave CO2 laser resurfacing is used to improve photodamage, wrinkles, and acne scarring by surface ablation and by using heat to activate natural collagen production and dermal remodeling. In this study, the author examined the efficacy and safety of nonincisional continuous wave fractional CO2 laser blepharoplasty in the upper lid. Standard lid measurements including margi...

Ablative fractional carbon dioxide (CO2) lasers have been widely used for several types of cosmetic dermatosis. A number of previous studies have evaluated this technique in animals or human beings by observing morphologic changes using an invasive modality such as skin biopsy. In this study, we assessed in vivo skin changes after CO2 ablative fractional laser treatment in a mouse model using n...

Laser equipment is capable of performing ablation and incision while providing hemostasis, and is widely used in intraoral surgery where bleeding can often occur(1). One of the oldest types of laser equipment is CO2 laser. The wavelength of CO2 laser (10.6 μm) is strongly absorbed by water, which means that CO2 laser is suitable for efficient ablation and incision of soft tissues that contain l...

CO2 laser-driven ion acceleration has been used to generate monoenergetic, MeV proton beams from a gas jet plasma. Use of a gas jet is advantageous because it offers interactions at a density around the critical plasma density for 10 μm pulses (10 cm) and can be run at a repetition rate of 1-100 Hz. This opens the possibility to create a variable species ion source easily switchable from proton...

We investigated the effects of laser wavelength on the atomic, ionic, and radiative emission from laser-produced tin plasmas. For generating plasmas, planar tin targets were excited using either high intensity neodymium-doped yttrium aluminum garnet Nd:YAG, 1.06 m or carbon dioxide CO2, 10.6 m laser pulses; both are considered to be potential excitation lasers for an extreme ultraviolet EUV lit...

today laser has a lot of usage in medicine and dentistry. in the field of dentistry, laser is used in soft tissue surgery, sterilization of canals (in root canal therapy) and in restorative dentistry laser is used for cavity preparation, caries removal, sealing the grooves (in preventive dentistry), etching enamel and dentin, composite polymerization and removal of tooth sensitivity. the use of...

The first terawatt picosecond (TWps) CO2 laser is under construction at the BNL Accelerator Test Facility (ATF). TWps-CO2 lasers, having the order of magnitude longer wavelength than the well-known table-top terawatt solid state lasers, offer new opportunities for the strong-field physics research. For processes based on electron quiver motion, such as laser wakefield acceleration (LWFA), the a...

High power carbon dioxide lasers have successfully been used in drilling or cutting ngineering materials such as metals, polymers and ceramics over the years. Can a arbon dioxide laser be used to efficiently drill different rocks in a deep gas well? esearch sponsored by US Department of Energy has been carried out to answer this uestion. This paper will report the study results of using a super...

The aim of this case report is to present a histologically diagnosed oral lichen planus excised by the CO2 laser. Oral lichen planus is a chronic inflammatory mucocutaneous disease of unknown etiology. Different treatments have been used to manage this condition. A 46 year-old female was referred to the Laser Clinic of the Dental School of the Federal University of Bahia to excise a lesion char...
