Mr penguin..... may be a lpm video of the laser over 90 seconds? and the one with the dot on the paper as you move away from the laser?
and have you contact laser glow? showing them the laser start dropping power after 40 secs and the beam turn Tem01?
Hey folks,
I just got my 473nm from Laserglow about 2 days ago but noticed something very strange, and wrong...
Issue #1: Laserglow claims this laser has a duty cycle of 90sec. However, after only about 50sec. the host feels very warm to the touch already?!?!
Issue #2: The laser operates in TEM01 once you move far enough away from the device. Do keep in mind it is supposed to have a divergence of <1mrad. The room it is being run in is at 74degrees so it isn't too hot, nor too cold. I have also tried heating the laser in my hand and letting it run for 40sec. to see what happens.
I payed $549 for this laser, so I would expect nothing but perfection. My other two are just fine....never had a thing like this for DPSS. I do know 473nm can be tricky but isn't Laserglow supposed to check all this? Or am I overreacting? Below are some pictures of how bad it is and where the laser was placed.
Any help for a veteran? Thank you all!

Tell Laserglow you are not happy with it and wish to exchnge it for a different and better example. For the high price paid you want a better example or to return if for a refund.
Laserglow is nothing special -- just an overpriced Canadian reseller of CNI lasers--Laserglow gets what they get--what CNI ships them.
The laserglow Aquarius is mainly about the small size and being eye safe. If your goal is value I'd say you should look for just about anything else.Thanks Encap!
I did see that Justin mentioned that these 473nm pens do tend to go into TEM01 at times but my previous 473 from them never had this issue!
I think I may actually head back into JetLasers for my laser needs. Laserglow isn't worth this high price ugh.
I see Jetlasers has 473nm up to 100mW, for less then what I payed for this! YIKES!
Anyone know the duty cycles on it? Is it 100%?

nice the problem is resolved i guess?
Tried it again for 60sec. and no TEM01 mode It was mode shifting for a little though.
Also with a <1.5mrad divergence how big is the dot supposed to be oh 15-20feet away? Mine isn't a nice round dot, but is a little blurry about 50% the size of a penny?
Yay :beer:

An old time veteran here to help a posting veteran.
From what we talked about in PMs and from what I'm reading here, I believe your laser to be operating as designed.
I've had an Aquarius for nearly ten years. Mine was from the first batch of pulsed blue colored host 473nm lasers produced by CNI after they killed the grey host CW ones. These lasers are EXTREMELY temperature sensitive. If it's even slightly chilly, it'll drop modes. If it gets warm, it'll drop modes. If you look at it wrong, it'll drop modes lol.
Per your request, I measured the divergence of my laser. At the aperture, it is 1.5mm. At 16 feet, it's 7mm, which gives a divergence of 1.127 mRad. At the time I bought my laser, LG advertised <1.5mRad. To calculate your laser's divergence, use this link:
pseudonomen137's JScript mRad Calculator
If you're used to looking at custom diode builds that can get .2-.3 mRad divergences, this laser will look like it has horrendous divergence. It's also important to measure your laser when it is running at it's best. If its off peak and not in TEM00, the divergence will be noticeably worse.
