Development of Stable Mode-Locked Nd : YAG Lasers

Pulse Timing in CW Mode - locked Nd : YLF Lasers

The influence of various noise sources on CW mode-locked laser pulse timing is investigated. Measurements are performed on a Nd:YLF laser to confirm timing dependence on cavity length and acousto-optic modulator characteristics. Simple models are used to understand and predict the influence of thermal load on the modulator and to predict the sensitivity of timing to pump and cavity loss modulat...

Mode Locked Fiber Lasers

Stable mode-locked pulses from mid-infrared semiconductor lasers

Stable trains of ultrashort light pulses with large instantaneous intensities from mode-locked lasers are key elements for many important applications such as generate short pulses in the mid-infrared (3.5-20 µm) molecular " fingerprint " region relies on the down-conversion of short-wavelength mode-locked lasers through nonlinear processes, such as optical parametric generation [9-11] and four...

Modeling of Mode-Locked Lasers

Growing demand of communication networks requires ultra-short pulses. Ultra-short pulses can guarantee high data transfer and power. Fiber lasers, which are actively or passively mode-locked to generate ultrashort pulses, are termed as Mode locked fiber lasers. There are a number of methods available for mode-locking of lasers. We have discussed most of them in this paper. At the end a model of...

Comparison of SHR Mode IPL System with Alexandrite and Nd: YAG Lasers For Leg Hair Reduction.

OBJECTIVE Multiple lasers and light sources are currently available for hair removal and many studies comparing efficacy and safety exist. SHR mode IPL is a technique that gives the total energy in divided doses with fewer side effects. We compared a SHR mode IPL system with alexandrite and Nd: YAG lasers for leg hair reduction. MATERIAL AND METHODS Twenty-five female participants with skin t...
