Picosecond dual-wavelength fiber-based laser source for Guangzhou CCELAB
勠力同心為化學(xué)與精細(xì)化工廣東省實(shí)驗(yàn)室提供皮秒雙波長(zhǎng)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(guò)不懈地努力與溝通，在與德國(guó)WinWinTec 國(guó)際集團(tuán)和德國(guó)通快(TRUMPF)集團(tuán)Active Fiber Systems協(xié)作下，我們贏得了華南地區(qū)這個(gè)關(guān)于開(kāi)發(fā)具有兩種波長(zhǎng)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(jìng)標(biāo)。
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(diào)諧范圍。我們的用戶(hù)由中山大學(xué)中山醫(yī)學(xué)院和化學(xué)與精細(xì)化工廣東省實(shí)驗(yàn)室的研究人員組成，未來(lái)會(huì)把我們提供的SRS激光器集成到通用 SRS 顯微鏡中，以實(shí)現(xiàn)對(duì)生物材料進(jìn)行快速化學(xué)映射及用于制藥。此外，SRS 激光還被用于醫(yī)療診斷的SRS標(biāo)簽的開(kāi)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(xué)過(guò)程，其中三個(gè)電磁波與樣品體積相互作用并產(chǎn)生特征光信號(hào)。在對(duì)應(yīng)于拉曼共振頻率的一對(duì)這樣的波的差頻重合時(shí)，信號(hào)被大大增強(qiáng)。這些技術(shù)通常用于對(duì)活細(xì)胞或固定細(xì)胞或組織中的生物分子成像。它們具有無(wú)需標(biāo)記或染色的巨大優(yōu)勢(shì)。此外，光譜信息是在寬帶光源的幫助下獲得的。這些應(yīng)用的信噪比極大地受益于高重復(fù)率脈沖激光的應(yīng)用。
