我们提出了一种基于fabry-pérot腔，带有结晶$ _ {0.92} $ ga $ _ {0.08} $ as/gaas镜像涂料，融合二氧化硅（fs）镜像sibrates和20〜cm-long-long-love ultra-low apperiation（Ule lele fextister a flastiration flaff ile flopser f tescipers） $ \ mathrm {mod} \，σ_\ mathrm {y} = 7 \ times 10^{ - 17} $的热噪声平台在一秒钟的平均时间中。该腔具有圆柱形形状，安装在十点。它在三个笛卡尔方向加速的分数频率的敏感性为$ 2（1）\ times 10^{ - 12} $/（ms $^{ - 2} $），$ 3（3）\ times 10^{ - 12} { - 12} $/（MS $^{ - 2} $）和$ 3（2} $）和$ 3（MS $ 3（1）属于针对可运输系统的最低加速度敏感性。激光系统的不稳定性达到$ \ mathrm {mod} \，σ_\ mathrm {y} = 1.6 \ times 10^{ - 16} $
We present a transportable ultra-stable clock laser system based on a Fabry-Pérot cavity with crystalline Al$_{0.92}$Ga$_{0.08}$As/GaAs mirror coatings, fused silica (FS) mirror substrates and a 20~cm-long ultra-low expansion (ULE\textsuperscript{\textregistered}) glass spacer with a predicted thermal noise floor of $\mathrm{mod}\,σ_\mathrm{y} = 7 \times 10^{-17}$ in modified Allan deviation at one second averaging time. The cavity has a cylindrical shape and is mounted at ten points. Its measured sensitivity of the fractional frequency to acceleration for the three Cartesian directions are $2(1) \times 10^{-12}$/(ms$^{-2}$), $3(3) \times 10^{-12}$/(ms$^{-2}$) and $3(1) \times 10^{-12}$/(ms$^{-2}$), which belong to the lowest acceleration sensitivities published for transportable systems. The laser system's instability reaches down to $\mathrm{mod}\,σ_\mathrm{y} = 1.6 \times 10^{-16}$
