Picosecond dual-wavelength fiber-based laser source for Guangzhou CCELAB
勠力同心為化學與精細化工廣東省實驗室提供皮秒雙波長光纖激光源
It took a lot of heart and sweat, but now it's done: WinWinTec International Group and TRUMPF Group Active Fiber Systems have won a bidding competition from a southern China research group to develop a dual-wavelength picosecond fiber laser for Stimulated Raman Scattering (SRS) microscopy.
經(jīng)過不懈地努力與溝通，在與德國WinWinTec 國際集團和德國通快(TRUMPF)集團Active Fiber Systems協(xié)作下，我們贏得了華南地區(qū)這個關于開發(fā)具有兩種波長的用于受激拉曼散射的皮秒光纖激光器(SRS)顯微鏡的研究小組的競標。
With the SRS laser, we address a tun ability rangefrom 1000 to 3300 cm-1with a spectral bandwidth of <10cm-1 (output 1) and <15cm-1 (output 2), respectively. For our users, which are researchers from the Zhongshan School of Medicine, Sun-Yat-Sen University, and the Chemistry and Chemical Engineering Guangdong Laboratory, we will integrate it into a general-purpose SRS microscope to achieve rapid chemical mapping in biological materials and pharmaceuticals. Furthermore, the SRS laser will be used for developing SRS tags for medical diagnosis.
使用Active Fiber Systems研發(fā)的 SRS 激光器，我們能夠提供在光譜帶寬<10cm-1（輸出 1）或<15cm-1（輸出 2）從 1000 至3300 cm-1 的可調諧范圍。我們的用戶由中山大學中山醫(yī)學院和化學與精細化工廣東省實驗室的研究人員組成，未來會把我們提供的SRS激光器集成到通用 SRS 顯微鏡中，以實現(xiàn)對生物材料進行快速化學映射及用于制藥。此外，SRS 激光還被用于醫(yī)療診斷的SRS標簽的開發(fā)。
Our SRS lasers involve third-order nonlinear optical processes where three electromagnetic waves interact with the sample volume to generate a characteristic optical signal. Upon coincidence of the difference frequency of a pair of such waves corresponding to the frequency of a Raman resonance, the signal is greatly enhanced. These techniques are typically employed to image bio-molecules in living or fixed cells or tissues. They offer the great advantage to not require any sort of labeling or staining. Additionally, spectral information is obtained using broadband light sources. The signal-to-noise ratio of these applications benefits greatly from the application of pulsed lasers at high repetition rates.
我們的 SRS 激光器采用三階非線性光學過程，其中三個電磁波與樣品體積相互作用并產(chǎn)生特征光信號。在對應于拉曼共振頻率的一對這樣的波的差頻重合時，信號被大大增強。這些技術通常用于對活細胞或固定細胞或組織中的生物分子成像。它們具有無需標記或染色的巨大優(yōu)勢。此外，光譜信息是在寬帶光源的幫助下獲得的。這些應用的信噪比極大地受益于高重復率脈沖激光的應用。
