Lock q pulse to available pulse widths by laser source

[Aaron.F (Aaron)]

I’m with you @dusan_fs

@MikeyH, some/most MOPA/UV sources can’t control the Q-Pulse value continuously.
Ideally, they would run with the closest possible value, but we’ve seen laser sources that just take the last known pulse duration if you ask it to fire at an unsupported value.

@Dannym

DOES NOT “ROUND” TO A NEARBY PULSE EITHER WAY, it will ignore the q-pulse command and and use the last valid Q-pulse it had. So your tests will be total junk if you try a test pattern at 30ns, 20ns, 10ns, and 5ns. The 10ns and 5ns will actually fire a 20ns pulse. Or, 5ns would give you the 150ns pulse if that’s the last valid one it saw.
