Hi,
so I decided to have a go at building custom Q-switched Nd:YAG laser. I'm hoping to go with diode pumping as sound of flashlight constantly firing is tiring after few hours. I found what seems to be good deal on fiber coupled 808nm pump sources but I have problem identifying connector and core diameter of required fiber. I can't post link but googling

Coherent FAP800-50W​

should show multiple ebay offers

Thanks.
It's sad to see that output fiber bundles are more expensive than laser sources themselves.
