Another laser and the second from OPOTEK this year: an IR Opolette 2940<\/a>. It is fixed wavelength at 2940 nm for no other reason than that is the Er:YAG laser<\/a> wavelength. It is possible to manually adjust the internal optics to generate light from 2700 to 3100 nm.<\/p>\n

\"OPOTEK<\/a>

This laser has its roots in the STTR grant<\/a> that I had with OPOTEK starting in 2001 (awarded when I was at Emory but moved immediately to LSU in the first year of Phase I). Our goal was to build an OPO with the capabilities of the Mirage 3000B<\/a> but in a smaller package.<\/p>\n

\"OPOTEK<\/a>

The left port gives access to the Nd:YAG laser<\/a> fundamental at 1064 nm and the right port is the 2940 nm mid-IR at about 3 mJ per pulse at 20 Hz. Plenty of energy when focused to efficiently ablate thin films (similar to our wavelength tunable IR Opolette<\/a> which you can see ablating things here<\/a>.)<\/p>\n","protected":false},"excerpt":{"rendered":"
