I purchased one of these out of sheer curiosity. Being so used to the DPSS 532 nm lasers I wanted to see what this pure diode based 515 nm beam looked like. It is beautiful! its beam looks somewhat like an emerald green color LED, but of course much brighter. I matched mine up with the AIX-ALM-MT-1 aluminum mount and started to use it in my modest light shows. It is a tiny unit, but very bright. So glad I indulged my curiosity. it would be great if there was 50 to 100 mW versions available here. I drive mine with the AIX-PST-3V5A power supply set at about 3.3 volts with no problems.
