Q:

Laser induced damage in BBO crystal

Does the repetition rate [Hz] of a IR (1035 nm) pulsed laser play a role in the damage threshold of a BBO crystal?

A:

Because BBO is transparent there really shouldn't be much in the way of heating effects, so it shouldn't play a significant role here, but those are some pretty extreme laser parameters. With 40W of power you'll always be running the risk of damage, but I'd be more concerned about dust or glue damage - is this for a thick BBO, or a thin one on a substrate?
