Treatment of Melasma with the Photoacoustic Twin Pulse Mode of Low-Fluence 1,064 nm Q-Switched Nd:YAG Laser
BACKGROUND Low-fluence 1,064 nm Q-switched Nd:YAG laser has been widely used for the treatment of melasma. Although new Q-switched Nd:YAG lasers with photoacoustic twin pulse (PTP) mode have been recently developed for high-efficiency, there is limited information available for the new technique. OBJECTIVE This study was designed to investigate the efficacy and adverse effects after few sessi...
متن کاملTreatment of Melasma with Pulsed-Dye Laser and 1,064-nm Q-Switched Nd:YAG Laser: A Split-Face Study
Background Melasma is an acquired pigmentary disorder that is often therapeutically challenging. Recent evidence suggests that vascular abnormalities are involved in melasma pathogenesis. Pulsed-dye laser (PDL) is considered as standard therapy for vascular lesions. Objective To assess the efficacy of PDL combined with low-fluence Q-switched Nd:YAG laser (QSNY) in the treatment of melasma. ...
متن کامللیزر Ce:Nd:YAG با دمش دیود نورگسیل و سوییچ Q انفعالی
The experimental study of passively Q-switched, LED-pumped Ce:Nd:YAG laser is reported. The active medium is a 3 mm diameter laser rod with 60 mm length; it is optically pumped with four segments of blue LEDs at 460 nm, with each segment consisting of 32 single LEDs. The 14 cm length optical resonator with 2 dielectric mirrors and the reflectivity of 99 and 93 percent at 1064 nm produced more t...
متن کاملTreatment of melasma by low-fluence 1064 nm Q-switched Nd:YAG laser.
BACKGROUND Low-fluence 1064 nm Q-switched Nd:YAG laser has recently been shown to be effective for the melasma treatment. OBJECTIVE The purpose of this study is to evaluate the clinical efficacy and safety of low-fluence 1064 nm Q-switched Nd:YAG laser treatment of melasma in Asian patients. METHODS Fifty patients with melasma underwent 15 weeks of weekly treatments, using a Q-switched Nd:Y...
متن کاملLidar-radar velocimetry using a pulse-to-pulse coherent rf-modulated Q-switched laser.
An rf-modulated pulse train from a passively Q-switched Nd:YAG laser has been generated using an extra-cavity acousto-optic modulator. The rf modulation reproduces the spectral quality of the local oscillator. It leads to a high pulse-to-pulse phase coherence, i.e., phase memory, over thousands of pulses. The potentialities of this transmitter for lidar-radar are demonstrated by performing Dopp...
