All fiber-based Yb-doped high energy, high power femtosecond fiber lasers.
Two all fiber-based laser systems are demonstrated to achieve high energy and high average power femtosecond pulsed outputs at wavelength of 1 µm. In the high energy laser system, a pulse energy of 1.05 mJ (0.85 mJ after pulse compressor) at 100 kHz repetition rate has been realized by a Yb-doped ultra large-core single-mode photonic crystal fiber (PCF) rod amplifier, seeded with a 50 µJ fiber ...
متن کاملYb Ring Doping in High-Order-Mode Fiber for High-Power 977-nm Lasers and Amplifiers
We numerically model the performance of highpower 977-nm fiber lasers and amplifiers pumped at 915 nm, in which the Yb is doped in a ring inside the core of a high-ordermode (HOM) fiber. Light in the spatially coherent LP07 mode is amplified in the fiber, and then coupled to the LP01 mode by longperiod gratings. For the laser, it is found that parasitic oscillation on the 1023-nm four-level tra...
متن کاملModeling and Optimization of High-Power Nd-Yb Codoped Fiber Lasers
High-power continuous-wave Nd-Yb codoped fiber lasers (NYDFL) are analyzed, based on a rate-propagation equations model. The model takes into account energy transfer between Nd and Yb, as well as cross relaxation between Nd ions, and contributions from high-order modes to the amplified spontaneous emission (ASE). Examples of cladding-pumped NYDFLs with distributed Bragg reflector (DBR) at eithe...

This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.
متن کامل3C Yb-doped Fiber Based High Energy and Power Pulsed Fiber Lasers
3C fiber technology advances the performance frontier of practical, high-pulse-energy fiber lasers by providing very large core fibers with the handling and packaging benefits associated with single mode fibers. First-generation fibers demonstrate scaling to > 240 W average power coincident with 100-kW peak power in 1-mJ, 10-ns pulses while maintaining single-mode beam quality, polarized output...
