Paper Abstract

A subterawatt fs laser complex with a power in a pulse P less than or equal to 0.15 TW is constructed. Our experiments show that axicon focusing of such laser light in transparent dielectric leads to formation of a long hollow channel with micron-order transverse dimensions. It is found that effective (approximately 10-3) generation of harmonics of incident light takes place in plasma appearing under axicon focusing. The discussion of the results obtained is presented.
