Advances in All-solid-state Laser for Novel Low-dimensional Material Saturated Absorbers(Invited)

全固态脉冲激光器因其大能量、短脉冲等特点在医疗、军事、工业和科学研究领域都发挥着重要作用。被动调Q和锁模是产生全固态脉冲激光的两种最有效的技术,其中,饱和吸收体是对激光输出参数有很大影响的关键器件。近年来,以碳纳米管、石墨烯和黑磷等作为代表的新型低维材料饱和吸收体因其制备过程简单、制作成本低廉、光学响应带宽较宽等优点得到了广泛的研究。综述了一些新型低维饱和吸收体材料:新型过渡金属二硫化物、三元硫族化合物、MXene、单元素烯类材料以及低维纳米结构在全固态脉冲激光调制领域的研究进展,并对新型低维材料饱和吸收体的未来发展进行了展望。

All-solid-state pulsed lasers play an important role in medical,military,industrial and scientific research fields for its high energy and short pulses. Passive Q-switching and mode-locking are the two most effective techniques for generating all-solid-state pulsed lasers. Among them,the saturable absorber is the key device that has a great influence on the laser output parameters. In recent years,novel low-dimensional material saturable absorbers represented by carbon nanotubes,graphene,and black phosphorus have been widely studied due to their convenient preparation process,low fabrication cost and wide optical response bandwidth. The research progress of some novel saturable absorber materials such as novel transition metal dichalcogenides,ternary chalcogenides,MXenes,single-element alkenes and low-dimensional nanostructures is reviewed in all-solid-state pulsed laser modulation. The future development of novel low-dimensional material saturable absorbers is also prospected.
