特征
Quasi-phase Matching in Periodically Poled Crystals
MixTrain 2 optical schematic
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.
包括所有需要的光學元件
MixTrain包含必要的所有光學組件，輸入基頻激光后，在周期極化晶體中混頻，從輸入光束中分離所需要的和頻光（SFM）或者差頻（DFM）輸出。設計以包含一個校準輸出的透鏡，以及一個隔離器阻止回射光的帶來的損傷。
自動波長設置，寬掃描范圍
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.
兼容的功率傳感器
要驗證和分析 MixTrain 激光器的輸出功率，我們推薦使用 Ophir 2A-BB-9 (7Z02767) 熱功率傳感器和 Centauri 激光功率計。 有關此激光測量設備的更多信息，請訪問 網站。 其他 Ophir 傳感器和儀表也可能適用于 MixTrain，詳細情況取決于具體應用。 Ophir 還與激光系統開發人員合作，實現嵌入式光束診斷，提供了監控系統性能的OEM 解決方案。
