There is a wealth of information here on the GF forum, but it’s sometimes a little difficult and time-consuming to sort through all the posts. I see a lot of what seems to be useful, concise information in Laser University (http://www.laseru.com/). The subscription price is fairly high, but they do have a 7-day free trial.
Is anyone subscribed to Laser University? Tried the trial? Experiences? Recommendations?
