The 10Q20UF.40 Chirped Mirrors for Ultrashort Pulses is a 1.0 inch (25.4 mm) diameter, 6.0 mm thick, laser chirped and is optimized for 700 - 900 nm. When transmitting an ultrashort pulse laser beam through a number of optical components, the pulse will spread and become chirped. Newport's Chirped Mirrors for Ultrashort Pulses are the solution to compensate for pulse broadening effects. These mirrors provide a negative group velocity dispersion to the incoming laser beam with every bounce off the surface. By setting up a two or three mirror configuration, the laser beam can bounce back and forth between the mirrors many times to compensate for pulse dispersion effects.
These mirrors can be mounted into Newport's patented clear quadrant mounts to create the closest separation between two mirrors to allow for a large number of bounces between elements (U.S. Patents: 6,304,393; 5,930,057, and 6,016,230). The high reflectivity of the mirror will preserve the laser beam intensity. Designed to reflect over 99.8% from 700 to 900 nm, this mirror is ideal to use with Spectra-Physics Tsunami®, Spitfire® Pro, or Mai Tai® lasers. Careful thin film design and advanced coating processes result in a mirror with maximum reflectivity, high bandwidth and negative Group Velocity Dispersion. This general purpose chirped mirror is optimized for use with 20 fsec pulses and longer.


10 q20uf。超短脉冲的40个啁啾反射镜直径1.0英寸(25.4 mm)，厚度6.0 mm，激光啁啾，适用于700 - 900 nm。当超短脉冲激光束通过多个光学元件发射时，脉冲会扩散并发出啁啾。纽波特的超短脉冲啁啾反射镜是补偿脉冲展宽效应的一种解决方案。这些反射镜每次反射到入射激光束表面时，都会产生负群速度色散。通过设置两个或三个镜像结构，激光束可以在两个镜像之间来回多次反射，以补偿脉冲色散效应。这些镜子可以安装在Newport专利的clear quadrant支架上，使两面镜子之间的距离最接近，从而允许元素之间产生大量的弹跳(美国专利:6,304,393;5930057年和6016230年)。反射镜的高反射率将保持激光束的强度。旨在反映超过99.8%从700年到900纳米,这面镜子是理想的使用Spectra-Physics海啸®,喷火式战斗机®Pro,或美态®激光。精心的薄膜设计和先进的镀膜工艺使镜面具有最大的反射率、高带宽和负群速度色散。这个通用的啁啾反射镜是优化使用与20 fsec脉冲和更长。
