Software developer (in love with C++). Hardware geek (FPGA's, STM32, AVR, crazy stuff from discrete components), love LED indicators (7-segment, alphanumeric). Trying to understand ASIC design & manufacturing better at the moment. Also, trying to wrap my head around lens design, but that is not going to be that easy.

comment Replacing 28.8Mhz TCO with up-converted GPSDO 10Mhz signal?
One should just remember that phase noise of PLL might be higher than one of the crystal itself.

comment Shaving Quartz Crystal for New Frequency
If you want to get fancy, you can try to find a Q-switched laser nearby, and try to ablate the material from the crystal edge. This should induce less defects to the surface. This is something which was not available in the prime age of the crystals.

comment Non-semiconductor CW laser types for 445-465nm
@CuriousOne I assume line of the atom itself and line in practical crystal is different. Also, not every line could be realized in a crystal and finally not every line is suitable for a laser... So it might be extremely hard to get to practical system from this list...
