I have your Trestles 50 femtosecond oscillator product and it has worked well. Now for the another application, I want to change the repetition rate of the oscillator from 82 MHz to 75 MHz. Is it possible to change by just moving output coupler back? Or should we change some other optics? Can you let me know detail and background about changing the repetition rate?


Yes it is possible to change the repetition rate by moving coupler and back reflection mirror back. There is no need to change any optics. Important tip: try to keep the same relative relation between the lengths of the cavity shoulders.
