High-Power Single-Frequency Fiber Lasers
Single frequency laser sources are desired in many applications. Various architectures for achieving high power single frequency fiber laser outputs have been investigated and demonstrated. Axial gain apodization can affect the lasing threshold and spectral modal discrimination of DFB lasers. Modeling results show that if properly tailored, the lasing threshold can be reduced by 21% without sac...

متن کاملElectrical alternative to pulsed fiber-delivered lasers in microsurgery
An electrical system based on a tapered microelectrode has been developed for generation of high voltage sub-microsecond discharge in physiological medium. Different types of the resulting pulses of current are investigated as well as the dynamics of the associated cavitation bubbles. A highly localized zone of power dissipation—about 20 mm in size—results in a low threshold energy of cavitatio...
متن کاملHigh-power pulsed fiber lasers and their evolution
Fujikura has achieved an output power of 30 W from a Q-switched pulsed fiber laser with a pulse width about 100 ns for the first time in the world. Following the achievement, we commercialized a 70 W output pulsed fiber laser . In the article, we describe our activities on high-power pulsed fiber lasers, and introduce our 70 W output products. Fujikura’s advanced and original functions of pulse...
متن کاملSingle Crystal Fiber for Ultrashort Pulses Lasers
Driven by the micromachining industry, where short pulses mean precision and power equals process speed, short pulse width high power lasers are in high demand. Whereas the MOPA (Master Oscillator Power Amplifier) is the current preferred architecture, it still suffers from performance limitations and high costs associated with system complexity and power amplifier limitations. A new amplifier ...
