特征
Quasi-phase Matching in Periodically Poled Crystals
The MixTrain utilizes quasi-phase matching in periodically poled crystals for sum- or difference frequency mixing of two cw-lasers. The system uses a motor controlled translation stage for changing the period of the crystal and a temperature stabilized oven capable of heating up to 180°C. All optics for beam shaping, polarization control, beam combination, and beam separation are included. An optical diode isolates the fiber laser input from back reflections from the setup. Periodically poled mixing crystals are mounted in a removable configuration to allow for alternate fiber input wavelengths. The mixing crystals are housed in a temperature stabilized oven with motorized control, providing hands free tuning over >100 nm of the visible spectrum.
Sum Frequency Mixing ~480 to 670 nm
Sum frequency mixing provides visible wavelengths from 480 to 670 nm. Typical tuning curve is shown when sum mixing a 4.5 W Matisse output and 1550 nm single mode fiber laser output with 10 W. When pumped with the Matisse C and the appropriate fiber laser the MixTrain provides hands-free, all solid state output from 422–670 nm for SFM, an attractive and versatile alternative to a CW dye laser.
Difference Frequency Mixing ~1.1 to 4.5 µm
With Difference Frequency Mixing, the output of a ti:sapphire laser is mixed with a single mode fiber laser at 1064 nm, 1550 nm, or 1950 nm. Difference frequency mixing provides near to mid-IR wavelengths. Typical tuning curve is shown when difference mixing a 4.5 W Matisse output and 1550 nm single mode fiber laser output with 10 W. Flexible configuration of mixing and separating optics enables output from 1.1-4.2 μm for DFM, depending on fiber laser input.
包括所有需要的光学元件
MixTrain包含必要的所有光学组件，输入基频激光后，在周期极化晶体中混频，从输入光束中分离所需要的和频光（SFM）或者差频（DFM）输出。设计以包含一个校准输出的透镜，以及一个隔离器阻止回射光的带来的损伤。
自动波长设置，宽扫描范围
A motor controlled translation stage and temperature stabilized oven are easily software controlled. Manual adjustments are not required for tuning.
Multiple crystals can be mounted simultaneously for tuning across 100+ nm. Scan ranges without the change of crystal temperature are >20 GHz for visible and >60 GHz for IR tuning.
兼容的功率传感器
要验证和分析 MixTrain 激光器的输出功率，我们推荐使用 Ophir 2A-BB-9 (7Z02767) 热功率传感器和 Centauri 激光功率计。 有关此激光测量设备的更多信息，请访问 网站。 其他 Ophir 传感器和仪表也可能适用于 MixTrain，详细情况取决于具体应用。 Ophir 还与激光系统开发人员合作，实现嵌入式光束诊断，提供了监控系统性能的OEM 解决方案。
