Large aperture tapered fiber phase conjugate mirror in MOPA laser systems with high repetition rate and high pulse energy
چکیده انگلیسی

A large aperture tapered fused silica fiber phase conjugate mirror with a maximum 50.7% stimulated Brillouin scattering (SBS) reflectivity is presented, which is operated with 400 Hz pulse repetition rate and 36.5 mJ input pulse energy. To the best of our knowledge, it is the first time that over 50% SBS reflectivity is achieved by using solid-state phase conjugate mirror under such high pulse repetition rate and high pulse energy. With much higher pulse repetition rate of 500 and 1000 Hz, the maximum SBS reflectivity is 41.2% and 33.3%, respectively. A single-longitudinal-mode Nd:YAG laser is experimentally studied with master oscillator power amplifier (MOPA) scheme using such a tapered fiber as a phase conjugate mirror. A 101 mJ pulse energy is achieved at 400 Hz repetition rate, with a pulse width of 6 ns and a M2 factor of less than 2. The corresponding peak power reaches 16.8 MW.

Research Highlights
► Improve the geometry of a tapered fiber.
► Use the tapered fiber as a phase conjugate mirror in a MOPA laser system.
► Increasing the core diameter and increasing the tapered region are helpful.
► Significant improvement of the performances was achieved.
