Also, if your thread title was something along the lines of "Looking for information concerning a Lightwave Halfnote", instead of the title you're using, members with knowledge about that particular laser are probably more likely to join in with a constructive response.
As Norty mentioned, compared to the number of members who that are heavily into solid-state lasers, the number of members really knowledgeable about gas lasers are still relatively few and far between, so you might need a good catchy thread title to hook 'em!!
If you fill out your location info in your profile, you might luck out and find someone experienced relatively close by that could assist.
