摘要
利用高压SF_6气体中的受激布里渊散射作相位共轭镜,将其用于Nd:YAG激光谐振腔,得到了能量在100mJ左右的脉冲激光输出.与利用液体介质的受激布里渊散射相位共轭腔的激光输出相比,其光斑的空间模式大大改善,基本达到TEM_(00)模,功率密度在150MW/cm^2输出能量的稳定性也有所提高.
Using tho Stimulated Brillouin Scattering (SBS) in high pressure gas SF6 as a phase conjugating mirror in a Nd:YAG laser resonator, we have got laser pulses with the pulsa energy of about 100 mJ. The spatial mode of output beam is much better than the output beam from the phase conjugate resonator based on the SBS in liquids. The power density of about 150MW/cm2. And nearly TEM00 mode are obtained. The stability of tho output energy is also increased.
