stabilizer use case for intensity stabilization of short-duration pulsed laser

zicheng

Hi, I am looking if anyone used SINARA stabilizer in stabilizing pulsed lasers intensity. Was SINARA stabilizer designed in a way that supports stabilization of short-duration laser pulse (_hundreds of microseconds to ~ seconds), or is SINARA stabilizer more widely applied on long-term intensity stabilization?

looking to hear others' suggestions/experiences in the context of this problem.

Hundreds of microseconds isn't exactly a "short" laser pulse.
If you mean generating a laser pulse that is as rectangular as possible (compensating for e.g. AOM heating up) it should be possible to use Stabilizer, perhaps with some firmware tweaks, and taking into account its latency (around 25µs with stock firmware, probably can be optimized).

Hi, thanks for the response! The ability to actually modify the firmware is really nice!

I wonder if
Has there been community works in reducing the latency by modifying the firmware? Realistically how much less than 25µs can we achieve.?
