Subpicosecond laser pulses at power levels in excess of 1 TW were channeled through hollow microcapillary tubes by use of a combination of grazing-incidence dielectric and plasma-wall reflection mechanisms. Maximum input and output intensities were 10(17) and 10(16) W/cm(2) through 50-microm radius by 3-cm-long glass microcapillary tubes with as few as two waveguide modes being excited. 133-microm radius tubes as long as 13 cm resulted in successful channeling with an extinction coefficient of 0.2 cm(-1) and a plasma-wall reflectivity of 80%.
通过使用掠入射电介质和等离子体壁反射机制的组合，功率超过1太瓦的亚皮秒激光脉冲被引导通过中空微毛细管。通过半径为50微米、长度为3厘米的玻璃微毛细管，最大输入和输出强度分别为10(17)和10(16)瓦/平方厘米，激发的波导模式少至两个。半径为133微米、长度达13厘米的毛细管成功实现了引导，消光系数为0.2厘米(-1)，等离子体壁反射率为80%。
