This is by far the best already assembled laser I have ever purchased. Lasever has a great product at a very good price. If you are looking for a 473 that's over spec check them out. When they say >80mW what they should have said was you're laser will be over spec.
10-10 Price paid, $405.00 it would have been $390.00 but I was asked to pay the Pay Pal fee. For a 473 of this power this is good price, beats buying a 65mW from Laserglow at $1200.00+
8-10 Delivery, I received this laser 7 days after it was shipped, I would have gotten it sooner but they were holding some kind of 2 day holiday in China. When it arrived it was very well packaged and protected. I got an over spec 473 laser, two key switches, a pin, an 18650 battery and a charger.
10-10 Customer Service, David Wu was awesome and LPF forum member Lasever was great as well. Both answered my emails promptly.
10-10 Laser Quality, I'm no expert nor would I dare take this thing apart but from what I can tell this laser is built very well, the host feels solid and is heavy thick aluminum. It looks exactly like a CNI host. The crystal used to produce the 473 is LBO and the beam spot is perfect round TEM0. :drool:
10-10 Power and performance, This laser peaked at 125mW once and has peaked at 112 consistently since then. The laser maintains an average power of 94-108 and never falls below 92mW for two straight minutes, I don't know what it would do after that as I don't run it for more than 2 minutes. The LBO crystal does not like to get warm and will mode shift to TEM 01 after running it for a while unless you allow a 5 minute cooldown to restore TEM0.
10-10 Safety, This laser has all 5 of the required FDA safety features, I wasn't worried about it getting past customs at all. As a class 3B it is still dangerous and not to be under estimated. It isn't all that far off from 500mW of class 4 445 due to the divergence, I calculated the NOHD at 287.18 with 100mW of power goggles are a must.
10-10 Beam Divergence, This is where this laser truly shines, it is after all a DPSS. I can't verify the measurements but according to Lasever's web site the divergence is .8 and the beam diameter is 2mm. The beam spot is great to behold and flickers like a star on video using a lens to zoom in at 105mm.
Oh yes right, pictures, ok in order from 1 - 9
1) Unwrapping the laser
2) Laser Accessories
3) Feels heavy and is made of thick aluminum, looks like a CNI host.
4) Beam shot comparison at exactly 72" at 105mm camera zoom 100mW 473 left vs 216 mW 445 right
5) Mode shift to TEM01 after running it over several two minute runs.
6) LPM test 108mW at 53 seconds
7) Beam shot in living room no time exposure, no smoke, no fog.
8) Beam shot outside at night 100mW of 473 looks the same as 400mW 445.
9) You Tube video of the LPM test sorry guys but I don't know how to link it, here is the You Tube Channel Lasever 100mW 473 hand held LPM test.
