Abstract :
We have demonstrated delivery of high power laser pulses through evacuated hollow core photonic crystal fiber. Two types of wavelengths which are the second harmonic of Nd:YAG (0.532 μm) laser and 5 ns Q-switched Nd:YAG (1.06 μm) laser have been coupled via PBG fiber. Under rough evacuation of the PBG fiber and with a good beam quality, 4 mW of outcoupled green laser and 600 μJ of outcoupled 1.06 μm laser were obtained the output beams show no change in their shapes.
