Nowadays, Erbium: YAG laser resurfacing of periorbital skin has become a very popular method of wrinkle reduction. Seven patients with Fitzpatrick skin phototypes of II to V were treated with a 2940 nm Erbium: YAG laser system for resurfacing of periorbital wrinkles. Photographic evalution performed before and after treatment. Patients were visited at 1,2,3,5,7,14,30 and 60 days after laser res...

A distributed feedback channel waveguide laser in erbium-doped aluminum oxide on a silicon substrate is reported. The optically pumped laser has a threshold pump power of 15 mW and emits 3 mW in single-frequency operation at 1545.2 nm wavelength with a slope efficiency of 6.2% and linewidth of 15 kHz. Keywords—Distributed feedback (DFB) laser; waveguide laser; erbium-doped laser; Bragg gratings...

Dentistry has a new weapon in the fight against tooth decay. This ‘light saber’ of dentistry is the erbium laser. The dental laser is the latest modern innovation for the 21st Century. Erbium lasers have proven safe and effective for the removal of tooth decay and cavity preparation, in addition to many soft tissue and hard tissue surgical procedures. The FDA approved the erbium laser for marke...

In this study, we report on the transient response of a passively mode-locked erbium fiber ring laser as studied by switching the optical pumping of the erbium doped fiber on and off. We confirm that the laser can maintain its mode-locking state even while the pump is modulated, and describe the laser behavior and its typical transient response upon abrupt changes in the intensity of the optica...

Background: Ablative laser treatment is widely used in dermatology. Different laser types are available. In contrast to that, the medical publication on erbium-YAG laser in dermatology often include small samples only. Objective: We want to demonstrate the versatility of classical erbium-YAG laser for medical conditions in dermatology in a single-center study. Materials and methods: This is a r...

Objective. The influence of Coherent Ultrapulse, TruPulse and Erbium: YAG laser skin resurfacing on survival of the skin flaps when performed simultaneously was evaluated. Material and methods. We used twelve female Yucatan minipigs in the study. Skin flaps including paniculus carnosus were raised on the animals’ back. The flaps were sutured into the defect under tension. We designed 4 experime...

The aim of this study was to evaluate the efficacy of autologous platelet-rich plasma (PRP) combined with erbium fractional laser therapy for facial acne or acne scars. PRP combined with erbium fractional laser therapy was used for the treatment of 22 patients, including 16 patients who suffered from facial acne scars and 6 patients who suffered from acne scars concomitant with acne. Whole bloo...

Erbium-doped solid-state laser systems have become an established tool in dentistry. The two most commonly used Erbium lasers in dentistry are Er:YAG and Er,Cr:YSGG, with a subtle but important difference in their respective laser wavelengths. There is also an important difference in the type of technology they utilize to energize the flashlamps. The conventional PFN (Pulse Forming Network) pul...

BACKGROUND Patients with atrophic scars commonly seek treatment for their removal but are often concerned about the prolonged recovery, short-lived results, and/or ineffectiveness of available therapies. A novel treatment using a 1,550-nm erbium-doped fiber laser to induce fractional photothermolysis of treated skin has been used to resurface photodamaged skin but has not been studied previousl...
