Thanks Mark,
That forum for pulsed Nd:YAGs will be awfully quiet, cuz our lasers don’t have maintenance other than a high OH quartz fiber replacement every 6 months or so. :biggrin:
In our latest design, we have even solved the slight “thermal lensing” issue that caused pulsed neodymiums to shift out of alignment every 12 months or so. No more!
But I appreciate the thought!!
Seriously, it is a great idea to have engineers peak in and participate in the discussions.
Erbiums really are a lot more “fussy” than neodymiums. Nd:YAGs like to operate “hot” and that won’t mess up the optics or alignment like it will with erbiums. My best recollection is that erbiums require a “chiller”–a refrigerator–to keep the Er:YAG and Er:YSGG as cool as can be.
Merry Christmas to all you observers of the day!
Bob
