High efficient actively Q-switched Ho:LuAG laser.
We present the room temperature Q-switched performances of a Ho:LuAG laser operated at 2.1 microm. At the repetition rate of 10 kHz, the maximum average output power of 9.9 W with a slope efficiency of 69.9% relative to absorbed pump power was obtained in Ho:LuAG laser. Also, the minimum pulse width of 33.0 ns was obtained, corresponding to the peak power was 30.0 kW.
متن کاملAll-optical, actively Q-switched fiber laser.
All-fiber lasers offer increased robustness and simplicity over other fiber laser systems. Current active Q-switching techniques for all-fiber lasers rely on electro-mechanical transducers to strain-tune an intra-cavity fiber-Bragg grating, which adds complexity and can lead to vibrational sensitivity. An all-optical technique for achieving active Q-switched operation is a more elegant approach...
متن کاملControlling Actively Q-switched Laser Output by Nonlinear State Feedback
Q-switched lasers are prevalent in applications that require high intensity laser in ultra short pulses. For many medical applications of Q-switched lasers, it is crucial to have smooth and controlled pulse shapes [1, 2]. In dermatological applications, for instance, an irregular shape or duration of a laser pulse during pigmentation removal can cause serious damage to the surrounding healthy t...
متن کاملModeling and optimization of Q-switched double-clad fiber lasers.
The numerical modeling of actively Q-switched fiber lasers is systematically presented. On the basis of typical Q-switched ytterbium-doped double-clad fiber lasers under forward and backward pump, the dynamic characteristics of pulse energy, pulse width, population inversion, and stored energy at tens-of-kilohertz repetition rates are studied by using the traveling-wave method. The laser perfor...
متن کاملHigh power VCSEL array pumped Q-switched Nd:YAG lasers
Solid-state lasers pumped by high-power two-dimensional arrays of vertical-cavity surface-emitting lasers (VCSELs) were investigated. Both end-pumping and side-pumping schemes of Nd:YAG lasers with high power kW-class 808 nm VCSEL pump modules were implemented. For one application 10 mJ blue laser pulses were obtained from a frequencydoubled actively Q-switched VCSEL-array dual side-pumped Nd:Y...
