We generated a low phase noise 16 GHz electrical signal of 20 Hz linewidth from a single 1 MHz linewidth diode laser. At 36 Ghz, our frequency angle mm-wave generator produced an electrical signal with an instrument resolution limited linewidth of < 1 kHz. Our approach uses a relatively low...
We demonstrate a high power all fiber single-frequency MOPA laser. The center wavelength of the single-frequency fiber laser seed is 1064 nm with a linewidth narrower than 20 kHz. A two-stage power amplification configuration is employed. A single-frequency fiber laser with an output power of ...
- 当`n`是一个标量，比如`contour(u,v,z,20)`，它表示等值线的总数，即期望画出20条等值线，此时的`[0, 0]`并不适用。- 如果`n`是一个向量，例如`contour(u,v,z,[1 2 3 4])`，它代表的是特定的等值线值，如z=1、2、3、4，这时`[1 1]`或`[0 0]`会分别对应于等值线值1...
contour(u,v,z,n)是画等值线 其第四个参数是控制等值线的值的 如果n是一个标量，那么解释为等值线的条数例如 contour(u,v,z,20)那么它会根据数据的范围画出20条等值线 如果n是一个向量，那么解释为需要等值线的值，例如 contour(u,v,z,[1 2 3 4])会画出z=1,2,3,4四个值的等值线...

Intracavity Laser Absorption Spectroscopy (ICLAS) was utilized to observe the $b ^{1}\\Sigma^{+}_{g}\\leftarrow X^{3}\\Sigma^{-}_{g}(u=0\\leftarrow u=0)$ transition of the oxygen A-band at 765 nm. The use of the high sensitivity of ICLAS (approx. $10^{-9} cm^{-1}$...

For the 0 MHzMHz laser, the normalized distributions of sodium atoms after recoil are simulated at 𝑡=10t=10 μμs, 20 μμs, and 35 μμs as in Figure 2. In order to study the effects of linewidth broadening on the mitigation of recoil, the linewidth of the continuous wave laser...
