摘要： An all-fiber Q-switched laser including a laser resonant cavity and a loop optical system is provided. The loop optical system is disposed inside the laser resonant cavity, and the all-fiber Q-switched laser generates a pulsed laser through the loop optical system. The loop optical system includes a plurality of wavelength-division elements and a saturable absorber. One of the wavelength-division elements is coupled with another one of the wavelength-division elements through corresponding first connecting fibers. Two ends of the saturable absorber are respectively coupled to second connecting fibers of the wavelength-division elements, wherein the saturable absorber and the two wavelength-division elements form a loop such that an auxiliary unsaturated light source can be transmitted in the loop.

摘要： The present invention relates to a Q-switching-induced gain-switched erbium pulse laser system, capable of generating erbium laser pulses within the 2.5 μm to 3.0 μm wavelength region, by means of Q-switching operation at 1.6 μm. At first, an Er3+-doped gain medium is pumped and Q-switched at the wavelength region from 1.58 μm to 1.62 μm, so that a Q-switched pulse is formed from the Er3+-doped gain medium. The Q-switched pulse results in an instant positive population inversion between the levels 4I11/2 and 4I13/2 of the Er3+-doped gain medium, followed by a gain-switched laser pulse at the wavelength region from 2.5 μm to 3.0 μm.

摘要： A pulsed laser system having a Tm3+-doped saturable absorber Q-switch unit, capable of outputting laser pulses sequentially by inputting a stable continuous-wave pump light source, is disclosed. When the gain excited in the Er3+ laser resonator exceeds the lasing threshold, the photons start resonating and being amplified in the Er3+ laser resonator. At the same moment, the Tm3+-doped saturable absorber Q-switch unit absorbs the resonant photons and quickly reaches the situation of absorption saturation. Then, sequentially Q-switched Er3+ laser pulses at 1570 nm are passively produced. In addition, the Tm3+-doped saturable absorber Q-switch unit can be designated as the gain material of a second laser resonator for producing a gain-switched Tm3+ laser pulse at 1950 nm after each of the Q-switched Er3+ laser pulses. Moreover, the Tm3+ and Ho3+ co-doped crystal can be designated as the saturable absorber Q-switch unit, for producing a gain-switched Ho3+ laser pulses at 2090 nm.
摘要翻译：公开了具有Tm3 +掺杂可饱和吸收器Q开关单元的脉冲激光系统，其能够通过输入稳定的连续波泵浦光源顺序地输出激光脉冲。当Er3 +激光谐振器激发的增益超过激光阈值时，光子在Er3 +激光谐振器中开始谐振并被放大。同时，Tm3 +掺杂的可饱和吸收剂Q开关单元吸收共振光子，并迅速达到吸收饱和的状态。然后，被动地产生在1570nm的依次Q开关Er3 +激光脉冲。此外，Tm3 +掺杂可饱和吸收体Q开关单元可以被指定为第二激光谐振器的增益材料，用于在每个Q开关Er3 +激光脉冲之后在1950nm产生增益转换Tm3 +激光脉冲。此外，Tm3 +和Ho3 +共掺杂晶体可以被指定为可饱和吸收体Q开关单元，用于在2090nm处产生增益转换Ho3 +激光脉冲。
