Description

全固态可见光被动锁模激光器 All-solid-state visible passive mode-locked laser

技术领域: FIELD:

[0001] 本发明属于激光设备与材料技术领域,涉及一种以石墨烯实现可见光锁模的全固态激光装置,特别是一种全固态可见光被动锁模激光器。 [0001] The present invention belongs to the technical field of laser equipment and materials, relates to solid-state laser apparatus mode-locked visible-graphene, in particular a passively mode-locked solid-state visible laser.

背景技术: Background technique:

[0002]目前,在普遍使用的全固态可见光锁模激光器设备中,都是先对钕离子激光晶体辐射的1.0微米波段激光锁模,再用非线性晶体进行频率变换而实现的。 [0002] Currently, in the mode-locked solid-state laser device visible in commonly used, neodymium ions are first irradiated laser crystals 1.0 micron band mode-locked laser, and then the nonlinear frequency conversion crystal is achieved. 例如:先用SESAM对Nd = YAG激光器的1064nm实现锁模,再用KTP晶体倍频获得532nm绿光锁模激光;或者先对1319nm实现锁模,再倍频获得660nm红光锁模激光,1319nm与660nm合频获得440nm蓝光锁模激光,由于激光频率变换不可能达到100%的转换效率,所以存在系统整体效率不高和稳定性降低的问题。 For example: first with SESAM for Nd = 1064nm achieved mode-locked YAG laser, KTP is then obtained 532nm green mode-locked laser; or the realization of the first clamping 1319nm, 660nm red frequency doubling and then mode-locked laser, 1319nm 660nm and 440nm blue frequency combiner obtained mode-locked laser, since the laser frequency conversion can not reach 100% conversion efficiency, there is high overall system efficiency and reduce the stability problem. 对现有技术进行总结归纳可知,阻碍全固态可见光锁模激光器发展的原因,一是缺少泵浦可见光激光晶体的半导体光源;二是缺少工作在可见光波段的可饱和吸收体;早在上世纪60年代就出现了镨(Pr)摻杂的可见光激光晶体,但是由于缺少波长450nm附近的半导体激光器(LD),全固态可见光激光器的发展一度处于停滞状态。 Summarizing the prior art can be seen, all solid reasons hindering the development of the visible light mode-locked laser, a visible light semiconductor light source one missing pump laser crystal; the second is the lack of work saturable absorber in the visible band; back in the 60 years there have been praseodymium (Pr) doped visible light laser crystal, but due to the lack of the semiconductor laser wavelength near 450nm (LD), the development of all-solid-state laser of visible light was at a standstill. 最近几年,随着半导体材料的发展,半导体蓝光激光器的出现为全固态可见光激光器的发展扫除了障碍,当前蓝光LD的输出功率和光束质量还比较低,但是从激光技术的发展趋势看,大功率、高光束质量的LD泵浦全固态可见光超短脉冲激光器是可见光激光发展的重要方向之一。 In recent years, with the development of semiconductor materials, semiconductor blue laser appears to eliminate the development of solid-state lasers visible obstacles, the current blue LD output power and beam quality is still relatively low, but from the look of the development trend of laser technology, large power, high beam quality of LD pumped solid-state visible ultrashort pulse laser is an important direction of development of the visible light laser. 当前较成熟的可饱和吸收体是半导体可饱和吸收镜(SESAM),制备SESAM需要金属有机化合物化学气相沉积等外延生长技术,过程复杂且成本高,而且常用SESAM材料的吸收带宽很窄,目前只能应用于近红外波段。 Current mature saturable absorber is a semiconductor saturable absorber mirror (SESAM), prepared SESAM requires metal organic chemical vapor deposition, epitaxial growth techniques, process is complicated and costly, and the SESAM absorption bandwidth used material is very narrow, only the current It can be used in the near-infrared band. 2004年,英国曼切斯特大学的AndreGeim和Novoselov首次通过机械剥离的方法从大块石墨上得到了石墨烯,它是继零维富勒烯、一维碳纳米管之后发现的由单层碳原子紧密堆积成二维蜂窝状晶格结构的单晶功能材料,由于石墨烯具有独特的电学、力学和光学性能,因而在高性能光电器件、复合功能材料以及能量存储等领域具有重要的应用前景。 In 2004, Manchester University, UK AndreGeim and Novoselov first obtained by mechanical separation from a chunk of graphite, graphene, which is a single layer of carbon following the zero-dimensional fullerenes, carbon nanotubes found in the one-dimensional atoms densely packed two-dimensional functional material to a single crystal lattice structure of the honeycomb, since graphene has unique electrical, mechanical and optical properties, which has important applications in the photovoltaic device of high performance, composite materials and functional fields of energy storage .
