These are not AR coated so they can except any IR
they are SHG 1 so they can except 554nm to 2600nm
808nm = 404nm and 946nm = 473nm and 980nm = 490nm and 1064nm = 532nm
808nm the tuning angle is 1Deg
1064nm the tuning angle is 4Deg
That proves it, These are LBO equivalents of the BBO crystals i had for Ti:sapphire lasers!
I would not suggest direct diode pumping these, even with KNBO3, which is the most efficient inorganic doubler known, the efficiency was something like 500mW in to 5mw shg out using a phase matched ECDL setup, with a direct setup it was something like 3mw out for about 5W in. In a stark contrast a q-switched laser gives much higher output- into the tens of mw with only a few hundred mw average power! KTP has a quirk that enables super efficient conversion without extreme phase matching precision.
