Femtosecond fiber laser输出100Fs得脉冲, 接fiber polarization controller,然
后接FR-103XL autocorrelator,autocorrelator的电信号输出接示波器。
谁用得熟练得朋友告知一下怎么 align FR-103XL autocorrelator,有什么窍门吗?调
了几天了,autocorrelation signal 得不到啊?读了manual, 也不得其解啊?

I have the following setup:
A pulse fiber laser(1ps) + 1x2 beam splitter + one paddle (fiber
polarization cotroller) on each arm of the splitter-> two inputs on the FR-
103XL (Femtochrome research, Inc).
就是用示波器观测这两个arm 的 crosscorrelation trace,但是捅鼓好几天了,死活出
不来信号?用过的牛人给点提示。

多谢你的阐述。
再次问了老板,发现我又错了。老板跟你说的差不多,我们有个FR-103XL
autocorrelator。Femtosecond fiber laser 连接这个autocorrelator,自己看了,这
个autocorrelator有个PMT探测器,它的输出接示波器,进而观察autocorrelation
signal.
老板实验室倒是有个4GHz和20Gs/S的示波器,但是他说你用不着这么高级的,去上网查
插,买个低级的能测autocorrelation signal的就行?
能否给点建议我该买什么参数的示波器满足我的要求?再次多谢

我们有个FR-103XL autocorrelator。Femtosecond fiber laser 连接这个
autocorrelator,autocorrelator有个PMT探测器,它的输出接示波器,进而观察
autocorrelation signal,不知道买个什么样的示波器(多少带宽和采样频率)就够用
了?谢谢
超短脉冲信息如下:
center wavelength: 1550nm
Repetition rate: 40MHz
Pulse width: 100 Fs

或者有朋友用过这个东东,来研究Ultrafast optics,想交流下经验。

What can I say? There are tons of reasons that you donot get output
from an auto-correlator. Last time, a Newport service engineer can
not get his auto-correlator to work in my lab.
Since apparently you are using a commercial one, my only suggestion
is that you should follow user manual or just call the technical
support.
