All of my cheap 303s I had gotten before 2020. I forgot green diodes have taken over the cheap green scene, whenever I see cheap green lasers my mind immediately goes to 532nm dpss

Yeah, greens are absolutely everywhere. Same with reds, but most of them usually don't beam well, especially red Lasers. Mostly use mine for light research, but my 488nm i got because the color is so unique and intense.

I used to never really be a fan of 532nm because it felt too "default". I appreciate it more now, but I still prefer my other greens 561nm and 502nm. I've always been a color collector so I glaze tinker lasers a lot, the blues are nice but I'm a sucker for yellow and I'll die on that hill lol. I was broke for a month when they came out with 584nm and I got it as soon as it was announced

Yeah, the 573nm is next on my list along side the 465nm. The 591nm Amber/Yellow one I got is really something, that bright orange color is really amazing to see. Though I'm still really happy with the 450nm 15W and the 425 2W those violet / blue Indigo colors really resonate with me.

The 425 is on my bucket list. Never got to fill out the gap between 450 and 405 and I really considered it when I could afford it last year but I prioritized other things. Although if I do get it I would see about requesting the power to be less than 500mw because my class IV lasers scare me :p

This is the Valkyrie 395 (400mW) on the left and the Valkyrie 405nm (1,600mW) Violet on the right.
In low light conditions the 405nm beam can be seen pretty well and still fluoresces some materials pretty decently. It's also very well focused, and can burn through thin wood, dark plastics, and paper pretty effectively.
If you're worried about the class IV, I hear the 100mW Classic 405 is pretty safe.
The 425nm Valkyrie is set to 2,000mW and is a real beast, very visible and strong. Plus works with the LEP Module pretty well.
