，可饱和吸收耦合输出镜，可饱和噪声去除腔，可饱和吸收体，太赫兹光电导天线<br /> <br /> 如果您对Batop<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>的价格、厂家、型号等相关信息有什么疑问，请联系我们获取Batop产品的最新信息。<br /> 我们的宗旨是以最好的质量最快的速度服务我们的客户。<br /> <br /> 德国BATOP公司是一家专门生长半导体可饱和吸收体等半导体光电器件的公司，主要产品包括：<br /> <br /> SAM半导体可饱和吸收镜 SAM - Saturable Absorber Mirror <br /> RSAM共振可饱和吸收镜 RSAM - Resonant SAM<br /> SOC可饱和吸收耦合输出镜 SOC - Saturable Output Coupler<br /> SANOS可饱和噪声去除腔 SANOS - Saturable Noise Suppressor<br /> SA可饱和吸收体 SA - Saturable Absorber <br /> PCA太赫兹光电导天线<br /> <br /> 其中SESAM，RSAM和 SOC 是用于稳定、自启动的DPSS被动锁模<a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>器最简单的锁模元件。<br /> <br /> 饱合吸收镜的封装方式有裸片，粘附在散热基座，和光纤尾端等方式。<br /> <br /> 半导体可饱和吸收镜（SESAM）的基本结构就是把反射镜与半导体可饱和吸收体结合在一起。底层一般为半导体反射镜，其上生长一层半导体可饱和吸收体<a href="http://opticalfilm.oecr.com" target="_blank" class="relatedlink">薄膜</a>，最上层可能生长一层反射镜或直接利用半导体与空气的界面作为反射镜，这样上下两个反射镜就形成了一个法布里-珀罗腔，通过改变吸收体的厚度以及两反射镜的反射率，可以调节吸收体的调制深度和反射镜的带宽。 <br /> <br /> 一般来说半导体的吸收有两个特征弛豫时间，带内热平衡 (intraband thermalization) 弛豫时间和带间跃迁 (interband transition) 弛豫时间。带内热平衡弛豫时间很短，在100-200fs左右，而带间跃迁弛豫时间则相对较长，从几ps到几百ps。带内热平衡弛豫时间基本上无法控制，而带间跃迁弛豫时间主要取决于半导体生长时衬底的温度，生长时的温度越低，带间跃迁弛豫时间越短。在SESAM锁模过程中，响应时间较长的带间跃迁 (如载流子重组) 提供了锁模的自启动机制，而响应时间很短的带内热平衡可以有效压缩脉宽、维持锁模。<br /> <br /> BATOP GmbH is a privately held innovative company founded in 2003 as spin-off from the University of Jena in Germany. BATOPs area of expertise are low temperature molecular beam epitaxy, dielectric sputter coating, wafer processing and chip mounting technologies.<br /> <br /> During the last years BATOP became a worldwide leading supplier of saturable absorbers for passive laser mode locking. The product portfolio of saturable absorbers consist of a wide range of different devices starting from saturable absorber mirrors (SAM™) up to saturable output couplers (SOC) and saturable absorbers (SA) for transmission applications. Up to now absorbers are available covering the most popular laser wavelengths from 800 nm up to 2.6 &micro;m.<br /> <br /> A second product family are photoconductive antennas (PCA) for terahertz radiation emission and detection. BATOP offers single gap antennas as well as microlens coupled high power large aperture interdigital antenna arrays. This antennas are designed for excitation wavelengths between 800 nm and 1550 nm.<br /> BATOP has a high percentage of research and development to improve his products continuously. Therefore we work together with our customers to best fit their needs.<br /> </td></tr></table> </div> <div id="comment_815541" class="cm"> </div> <div id="post_rate_div_815541"></div> </div> </div>
