Scaling of dissipative soliton fiber lasers to megawatt peak powers by use of large-area photonic crystal fiber

Abstract

We report an all-normal dispersion femtosecond laser based on large-mode-area Yb-doped photonic crystal fiber. Self-starting mode-locked pulses are obtained with an average power of 12 W at 84 MHz repetition rate, corresponding to 140 nJ of chirped pulse energy. These are dechirped to a near transform-limited duration of 115 fs. Experimental results are consistent with numerical simulations of dissipative soliton intracavity pulse evolution, and demonstrate scaling of 100 fs pulses to megawatt peak powers.

Multimodal fiber source for nonlinear microscopy based on a dissipative soliton laser

“…However, the higher starting average power in this system makes it possible to improve the noise performance of this source by optimization of the laser. Eventually, it may be advantageous to construct a dissipative-soliton laser with large- core fiber, which can directly produce 40 nJ pulses for pumping the OPO without amplification [32,33]. This would reduce the shot noise limit of the pump pulses even further, and eliminate the RIN added during amplification.…”

Tm3+-doped CW fiber laser based on a highly GeO2-doped dispersion shifted fiber

“…It has been predicted that ANDi fiber oscillators can be perfectly energy-scalable by fiber length scaling [17]. One can expect that the core size can also be enlarged without transition to the anomalous dispersion regime by fiber microstructing [16]. The analysis of this possibility is under way now.…”

“…7 demonstrates that the all-normal-dispersion (ANDi) regime of modelocking [14,15] is feasible for very small core radii. Such regime is of interest for generation of the energy-scalable femtosecond pulses [16]. It has been predicted that ANDi fiber oscillators can be perfectly energy-scalable by fiber length scaling [17].…”

Bending Analysis of a Dual-Core Photonic Crystal Fiber

“…The appearance of photonic crystal fibers (PCFs) [1][2][3][4][5][6][7][8][9][10] with silicaair microstructure is a milestone in the history of optical fibers, which have achieved excellent optical properties in birefringence [11][12][13][14][15][16], dispersion [17][18][19][20], single polarization single mode [21][22][23][24][25], nonlinearity [26][27][28][29][30], and effective mode area [31][32][33][34][35] over the past several years. It is well known that PCFs have shown excellent performances in applications such as optical communications [36][37][38], fiber lasers [39][40][41][42], supercontinuum sources [43][44][45][46] and also fiber sensors ...…”
