We present what is, to the best of our knowledge, the first pure-three-level Yb:CaGdO(BO) (Yb:GdCOB) laser emitting at 976 nm based on the F2-F2 transition, generally used for a quasi-three-level emission at 1032 nm. A maximum power of 782 mW at 976 nm has been achieved in continuous-wave (CW) operation pumped by a quasi-three-level Nd:SrLaAlO laser emitting at 902 nm. Moreover, a self-frequency-doubling CW blue laser has also been demonstrated with a maximum power of 133 mW at 488 nm.

Introduction: Uric acid (UA) is the risk factors for the development of arterial hypertension (AH). Development of alternative methods of UA level reduction becomes relevant. The aim - to determine th...
Breast reconstruction with implants can be complicated by symptomatic capsular contracture, especially after radiotherapy. A phase I, nonrandomized clinical trial demonstrated improvement in capsular ...
Unusual and exhaustive physical exercise can lead to muscle lesions depending on the type of contraction, intensity, duration, age, and level of conditioning. Different therapies have been proposed to...
Optical vortex Laguerre-Gaussian (LGl) modes have wide-ranging applications due to their annular spatial form and orbital angular momentum. Their direct generation from a laser is attractive, due to t...
We realize a 1 W all-fibered polarized compact and robust laser source at 852 nm for laser cooling of cesium atoms. The architecture is based on the sum-frequency generation of 1540 and 1908 nm las...
No single type of laser or set of laser parameters is appropriate for all type of irides. Pure Nd:YAG laser iridotomy is very effective in the light color irides. It was considered as the ...
The study hypothesis is a improved muscle fatigue resistance induced by low-level laser therapy applied between sets of intense exercises.
The purpose of the present study was to evaluate the effects of one session of aerobic exercise associated with low level laser therapy in lipolytic activity, lipid profile and inflammator...
There are two specific aims for this study. Aim 1 is to test whether low-level laser therapy (LLLT) can enhance the efficacy of fear extinction training in the modification of pathological...
The purpose of this research study is to determine if treatment with Low Level Laser Therapy (LLLT) is effective in treating the pain, numbness or tingling patients are experiencing follo...
Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli.
A degenerative disease of the AUTONOMIC NERVOUS SYSTEM that is characterized by idiopathic ORTHOSTATIC HYPOTENSION and a greatly reduced level of CATECHOLAMINES. No other neurological deficits are present.
