(a) Cut-back loss and simulation loss of our HC-ARF; Inset: SEM image of our HCARF; (b) Macro-bend loss measurements at bend diameters of 20, 16, 13, 8, and 4 cm; (c) Delivered green powers after different lengths of HC-ARF (2 m, 100 m, and 300 m) versus input green powers. (d) Beam quality measurements at the maximum output power for 300 m lengths of HC-ARF; Inset: Fiber output beam profile at the highest power level. Figure 2. (a) Simulated HC-ARF dispersion. Inset: Temporal profile of the optical pulse measured at the 300-m HC-ARF output. (b) HC-ARF output spectra for a 100-m fiber along with simulation results; Inset: Delivery fiber photo taken at the maximum output power. (c) 100-m HC-ARF output spectra with linearly and circularly polarized inputs. (d) 300-m HCARF output spectrum at maximum power and corresponding simulation results. Inset: Delivery fiber photo taken at the maximum output power. Figure 3. A comparison between the 15-m PCF spectrum, 15-m HC-ARF, and 300-m HC-ARF. Figure 4. Simulation of sub-nanosecond green pulse delivery in reduced-loss HC-ARFs. (a) Simulation of spectral bandwidth (Δλ) broadening at the output for different input peak powers. (b) Scalability of pulse delivery in air-filled HC-ARFs: the output peak powers at different input powers and at 1-1000 m of minimum 1.5-dB/km-loss HC-ARFs. The grey shaded area indicates the bandwidth for which gas vibrational Raman Stokes and anti-Stokes would be seen. The green shaded area indicates the bandwidth for which rotational Raman Stokes and anti-Stokes would be seen. The red shaded area represents possible high-energy-density induced damage. Figure S1. Cut-back loss and simulation loss of our HC-ARF (left); Cut-back transmission measurements at a fiber length of 402-m and 100-m (right). Figure S2. Beam quality measurements at the maximum output power for 2 m (a) and 100 m (b) lengths of HC-ARF, respectively. Insets: beam profiles of the corresponding output beams at the highest transmitted power levels. Figure S3.
