摘要

Multiple standing wave and traveling wave Ba(NO_3)_2 Solid State Raman Lasers (SSRLs) have been built and characterized. The Ba(NO_3)_2SSRLs were pumped by a 1338 nm wavelength Nd:YAG laser resulting in 1556 nm output wave-length. Folded Raman ring resonators have produced near-transform-limited spectral coherence via injection-seeding. Several different resonators have also produced near-diffraction limited spatial coherence, without seeding. A three-mirror ring configuration Ba(NO_3)_2 SSRL produced 1/5 wave peak-to-valley wavefront aberration, 175 mJ/pulse and 30 pulses per second while being pumped by lasers with a beam quality figure of merit M~2 > 15. The spectral and spatial coherence of the SSRLs is indicative of a rich phenomenology.
