"Photodarkening-Induced Phase Distortions And Their Effects In Single-Channel And Coherently Combined Yb-Doped Fiber Chirped Pulse Amplification Systems

This dataset contains which are used for generating Fig.2 to Fig.7. These figures are plotted using Matlab 2017
The figures are as follows:

Fig. 2. (a) Signal energy and accumulated B-integral and (b) total accumulated thermal phase as induced in the trailing edge of the pulse in 2-m fiber amplifier for different total PD propagation loss.
Fig. 3. Change in phase from the PD-free case for different total PD propagation loss in a fiber amplifier of length (a) 2 m and (b) 1.m. 
Fig. 4. Compressed pulses from the 2-m (a) and 1-m (b) fiber amplifier at different total PD propagation loss. 
Fig. 5. Pulses from CBC system with different amounts of total PD propagation loss in one channel only. (a) 2 m fiber (b) 1 m fiber. 
Fig. 6. Results of fiber amplifier shortened to 1.5 m with different PD losses. Evolution along the fiber of (a) energy, (b) B-integral, and (c) thermally induced phase difference between trailing and leading pulse edge. (d) phase change from PD-free case (e) compressed pulses from single channel (f) compressed pulses for two combined channels. 
Fig. 7. 7 (a) Combining efficiency and (b) RMS pulse duration of single channel and CBC systems for different total PD propagation losses for different fibers. The Yb-concentration is the same in the 2-m and 1.5-m fibers, and twice as high in the 1-m fiber.
