Hello everyone. Firstly can I take the opportunity to thank all contributors for your rich knowledge and the constantly helpful reminders about safety. About fifteen or more years ago I bought a Laserglow Aries green laser. (at least I think that's what it is) It's recently died on me, so I'm looking to replace it maybe with something a little more powerful. I've loved that laser but maybe the technology has moved on? Following advice provided on here I've been looking at the Sanwu Striker, however on Youtube reviews I've noticed the beam is a noticeably divergent rectangle even with he beam expander. Is this a product of the greater power? and possibly the diode type? Is there a laser anyone would care to recommend. I'm not interested in burning stuff, just a coherent stable preferably round beam. I have plenty of land here and live in the middle of nowhere so the safety of others is not a concern. Thank you for your help. I really appreciate it.
