Treatment of lentigines by a novel high power diode laser at 755 nm: a case report
The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...
متن کاملGrating Feedback in a 810 nm Broad-Area Diode Laser
Narrow linewidth, single spectral mode operation has been obtained in a high power, 810 nm broad-area diode laser in an extended cavity configuration with a grating as external reflector (grating feedback). For stable operation it was necessary to misalign the feedback slightly in the plane of the laser junction. Characteristics of the thus obtained laser system are a linewidth below 5 MHz, an ...
متن کاملLaser lipolysis with a 980 nm diode laser.
Laser lipolysis is recognized as an effective, non-surgical solution for fat removal and body reshaping. Its appeal lay in the procedure's ability to treat localized fat deposits and correct body asymmetries with apparent decreased risk compared to traditional liposuction. The energy emitted by the laser uses volumetric heating to destroy fat cells, contract skin and stimulate collagenesis. Alt...
متن کاملanalysis of laser-fat interaction through comparing 980 nm diode laser with 1064 nm nd:yag laser
results the simulation results showed that the penetration depth and temperature rise of 980 nm wavelengths were different from those of 1064 nm wavelength. it appeared that 1064 nm wavelength penetrated to deeper layers of tissue compared with 980 nm. moreover, temperature rise during 1064 nm irradiation led to temperature increase in allowable ranges. the findings proved the reason why 1064 n...
متن کاملFrequency Stability at the Kilohertz Level of a Rubidium-Locked Diode Laser at 192.114 THz.
The frequency stability of a 1560-nm diode laser, whose second harmonic was locked to (87)Rb sub-Doppler lines, was characterized by measuring the beat frequency relative to a 780-nm reference laser that was locked to sub-Doppler lines of another rubidium cell. The square root of the Allan variance reached a minimum value of 7.5 x 10(-12) in 1 s, which corresponded to frequency variations of 1....
