چکیده
An ultrafast fiber chirped-pulse amplification laser system based on coherent combination of 16 ytterbium-doped rod-type amplifiers is presented. It generates 10 mJ pulse energy at 1 kW average power and 120 fs duration. A partially helium-protected, two-staged grating compressor implemented to maintain the close diffraction-limited beam quality by avoiding nonlinear absorption in air.

Beam Combination and Control - Andrusyak 2 Fiber laser system with kW - level spectrally - combined output
Beam combining techniques have become an important tool in design of high-power highbrightness laser systems [1]. Maximum power that can be obtained from single high-power amplifiers is usually limited by thermal distortion of active medium and beam quality degradation in solid-state lasers or non-linear effects and active fiber damage in fiber lasers. Beam combining offers an alternative solut...
متن کاملYb-Doped Single-Mode Fiber CPA Laser System
High peak power laser systems of up to petawatt [1] are based on chirped pulse amplification (CPA) technique [2]. In the CPA laser system, ultrashort pulses from an oscillator are first stretched below the nonlinear pulse distortion threshold to reduce the peak power and the amplified pulses are recompressed at the output by a compressor. Stable ultrashort pulse oscillator is necessary for CPA ...

In recent years, the demand for the continuous wave (CW) fiber lasers of several kilowatts output power is increasing in use for metal materials processing. Fujikura group have all principal technologies required for constituting fiber lasers. We succeeded in commercializing the CW fiber laser of 4 kW output power by using those technologies. Our 4 kW CW fiber laser product has a high tolerance...
متن کاملTowards 100 kW fiber laser systems
Fiber lasers are rapidly gaining market shares for industrial applications due to compactness, high electrical-to-optical efficiency, high beam quality and low running cost. However, for directed energy weapons, fiber lasers have until now been unable to meet the requirements of military, where power levels around 100 kW are aimed for through combining of multiple, high beam quality lasers. The...
متن کامل1.1-J, 120-fs laser system based on Nd:glass-pumped Ti:sapphire.
We have developed an ultrashort-pulse laser system in which the final Ti:sapphire amplifier stage is pumped by the frequency-doubled output of a Nd:glass laser. The laser produces pulses with an energy in excess of 1 J on target and an estimated peak focused irradiance of 5 x 10(19) W/cm(2).
