Abstract

For delivery of femtosecond laser pulses, a flexible, hollow glass fiber with inner coating of silver and polymer is employed. By using the hollow fibers, ultrashort pulses with a pulse width of 196 fsec, energy of 700 mJ, and repetition rate of 1 kHz are transmitted with no damage on the fiber. The transmission loss is 0.13 dB in the 1.0-mm bore fiber and pulse broadening after transmission in 1-m long fiber is 17 fsec. Theoretical calculation shows that the numbers of transmitted modes in the fiber is estimated from the pulse broadening.
