Very true. Correct me if I'm wrong but 473nm uses an LBO crystal instead of a KTP crystal. And as far as I'm aware yellows can have shelf life problems. It's one of the reasons laserglow doesn't offer the PGL-3-C 589s. The didn't meet the quality and life expectancy limits.
Feel the same way at the moment, but it doesn't have to be today or tomorrow, but in 1-2 months time:shhh:
About that 1W 532nm news: if it's going to happen and the output is guaranteed to be at such a level, CNI's marketing attitude is an example other company sellers could be inspired by. Honestly, there's a good chance enough people/buyers are interested in this potentially groundbreaking GB deal...
Well I don't know all the details, but about a year ago LG was developing (might still be) a 589 with a longer run time than 30 seconds. but they were having issues getting them up to their quality control levels. I believe there is a thread on here talking about it in fact. as far as crystal degradation or simply fragility/not meeting MTBF requirements I don't know why they didn't get produced.
589 is not a common wavelength, has little demand, and can only be made on a very fragile and complex system by generating two lasing lines from a vanadate (1319 and 1064), summing them and then doubling the result. they're very hard to make and must maintain a specific temperature (or it wont lase) and are only about 1% efficient compared to a green which is probably closer to about 32%. I'm not saying you shouldn't buy one...but keep in mind that these lasers are very complex and only came around within the last few years. As awesome as they are, take it with a grain of salt and respect that they aren't going to be as reliable or long lasting as a typical more common DPSS system. If you buy one, don't be suprised if strange things happen while you run it....anything as simple as the kind of battery you're using can change how it behaves. Just recently I believe bloom got one and it has a multiline issue (or blessing :na
