Space debris poses an increasingly serious threat to satellites and spacecraft. Our project will aim to mitigate this problem using an array of kilowatt-class lasers, powered by photovoltaics. An experiment was implemented to study this using a directed energy system to completely vaporize or propel space debris out of Earth’s orbit. Common materials found in space debris were tested using a 60...

AIM The Er:YAG laser has proven to be effective and efficient in dental hard tissue ablation. The Minimally Invasive Dentistry (MID) approach in caries removal is to stop the disease process and to restore lost tooth structure and function, maximizing the health potential of the tooth. One of the most important concepts of the MID is to preserve as much as possible the dental tissue and this ap...

The latest technical improvements in the surgical armamentarium are remarkable. In particular, advancements in the urologic field are so exceptional that we could observe the flare-up of robot-assisted laparoscopic radical prostatectomy for prostate cancer and laser prostatectomy for benign prostatic hyperplasia (BPH). Photoselective vaporization of the prostate (PVP) and holmium laser prostate...

BACKGROUND Epidermal nevi have been notoriously difficult to treat due to their large size and often conspicuous location. Variable results have been obtained with different laser treatments, and scarring and/or incomplete removal is typical after excisional or other destructive modalities. OBJECTIVE To outline the successful use of a short-pulsed CO2 laser in the long-term eradication of epi...

This article reviews the current and potential applications of laser technology in nonsurgical therapy for the treatment of periodontal diseases. Based on its various characteristics, such as ablation or vaporization, hemostasis, and sterilization effect, laser treatment may serve as an adjunct or alternative to conventional, mechanical periodontal therapy. The Carbon dioxide (CO2) and the Neod...

Laser drilling in the percussion regime is commonly used in the aircraft industry to drill sub-millimetre holes in metallic targets. Characteristic laser intensities in the range of 10 MW cm−2 are typically employed for drilling metallic targets. With these intensities the temperature of the irradiated matter is above the vaporization temperature and the drilling process is led by hydrodynamic ...

hands, and eyelids, among other areas. When used on the eyelids, patients notice a tightening of the skin and reduction in dark circles. This laser is a good choice for patients with skin types I to IV (Table 6-2) and those who would like more aggressive treatment with more significant results than nonfractional nonablative laser, but without the downtime required with ablative laser resurfacin...

Laser explosive microfabrication was used to bond micrometre-thick aluminium films to both copper and silicon substrates. Bonding was observed in both systems for laser intensities greater than about 1 x 109 Wcm 2 and resulted in contiguous, uniform films when performed in a rough vacuum of 25 to 70 millitorr. At intensities greater than 9 x 109 Wcm -2 the transferred films were generally black...

Benign prostate enlargement (BPE) is a highly prevalent pathology (1). The main consequence of BPE is Bladder Outlet Obstruction (BOO). Patients with BOO may be bothered by voiding lower urinary tract symptoms (LUTS). Those men with BOO and significant LUTS which did not respond to clinical approaches may be candidate to surgical procedures. In patients with prostate volume inferior to 80-100 g...

Background: Irritative symptoms including prolonged urgency and dysuria after GreenLight laser photoselective vaporization (PVP) of benign prostatic hyperplasia (BPH) are common complication. We aimed to compare the incidence of postoperative irritative symptoms of GreenLight XPS (GL-XPS) 180W laser system with GreenLight KTP (GL-KTP) 80W laser system for the treatment of BPH and evaluate the r...
