Informations are based on Datasheets found in our office. I did not check if all AOM do excist or are working!

• IntraAction:
• ASM-1501M3: 150+-40 MHz for 257 nm and 1mm Dia beam: Is in use at SHG 2.
• ASM-1501LA3: 150+-40 MHz for 266 nm and 1mm Dia beam: Is working.
• ASM-852-5: 85+-15 MHz for 326nm and 2mm Dia beam: Is available.
• ASM-80: 80+-15 MHz for 440 - 700nm

Ther are also Datasheets of other companies like for example Crystal Tech. This are not listed yet. Fell free to complete this list!
