The M-FRG-KT FROG kit is based on the setup used in Newport Application Note 33 - Amplitude and Phase Characterization of Ultrashort Laser Pulses which describes the technique known as frequency-resolved optical gating (FROG). FROG is a technique that can be employed in a variety of experimental geometries. M-FRG-KT can be configured for two of these geometries: self-diffraction (SD FROG) for ultrafast amplified systems and second harmonic (SHG FROG) for ultrafast oscillators. The standard M-FRG-KT is optimized for Ti:Sapphire amplifiers centered at 800 nm or Ti:Sapphire oscillators covering 700-950 nm. For customers planning to use the standard kit with an ultrafast oscillator, please also order Newport part number 90015087, a mounted BBO crystal covering 700-2000 nm inputs, used to generate the second harmonic in the SHG FROG configuration. Custom versions can be configured over varying wavelength ranges between 400-2000 nm. No spectrometer is included in the standard kit, but can be included in a custom version. The data acquisition and display software included with this product has been tested in the experimental setup described in the application note. It will work only with specific spectrometers. Third-party freeware software is available for interpretation and analysis of complex FROG traces.

M-FRG-KT青蛙工具包是基于新港应用注33中使用的设置-超短激光脉冲的振幅和相位特性描述了被称为频率分辨光选通(FROG)的技术。青蛙是一种可以用于各种实验几何图形的技术。M-FRG-KT可以为这两种几何结构配置:超快放大系统的自衍射(SD蛙)和超快振荡器的二次谐波(SHG蛙)。标准的M-FRG-KT为钛:蓝宝石放大器优化，以800nm为中心，或钛:蓝宝石振荡覆盖700nm -950 nm。如果客户计划使用带有超快振荡器的标准组件，也请订购Newport part number 90015087，这是一个安装的BBO晶体，覆盖700-2000 nm的输入，用于在SHG FROG配置中产生二次谐波。定制版本可以配置在400-2000纳米的不同波长范围。标准组件中不包含光谱仪，但可以包含在定制版本中。本产品所包含的数据采集和显示软件已在应用说明中描述的实验设置中进行了测试。它只适用于特定的光谱仪。第三方免费软件可用于解释和分析复杂的蛙迹。
