High power all-normal-dispersion mode-locked Yb3＋-doped double-clad fiber femtosecond laser

摘要: 以芯径为30μm的掺Yb3＋双包层光纤为增益介质,利用非线性偏振旋转技术以及光栅-小孔结构组成的光谱滤波器提供有效的振幅调制,实现了稳定的全正色散耗散孤子锁模运转.激光器直接输出重复频率为76.6 MHz、平均功率达6.3 W的超短脉冲,单脉冲能量可达82 nJ.直接输出脉冲宽度为1.33 ps,经腔外压缩后的宽度为377 fs.通过调节光栅角度还实现了输出脉冲中心波长在1025—1078 nm范围内的调谐.

Abstract: A stable all-normal-dispersion dissipative-soliton mode-locked laser is demonstrated with a Yb3＋-doped large-mode-area doubleclad gain fiber,and nonlinear polarization evolution and spectral filtering composed of a grating and an aperture are exploited to produce sufficient amplitude modulation to shape pulses of this laser.The laser generates chirped pulses at a 76.6 MHz repetition rate,with an average power of 6.3 W,and a single pulse energy of 82 nJ.Pulse duration of the direct output pulse is 1.33 ps and it can be dechirped to 377 fs after externally compressed.By adjusting the grating,the central wavelength of the output pulses can also be tuned from 1025 nm to 1078 nm.
