400mW green laser torch /focusable/waterproof [OL-532-300] - $196.99 : Welcome to O-Like.com, Your source for laser products

does anyone have any info on this?

I just bought a 200mW green laser from here for about the same price, and then this came up. D: I know it probably wouldn't be 400mW, maybe 300mW or something? But even 300mW for that price is pretty good right?

any information on this would be awesome.

I don't think anyone has made a thread about this yet, but if they did I don't care if it gets deleted.

Well considering some1 reviewed a 1w 445nm in the same host, that laser is horrible for burning. Because you need to use the pin they provide to focus it, and your hand will be in the way of the beam, so you would have to turn it off, focus, and check. It should definately be atleast 350mw, o-like usually is up to spec

I guess if you want to buy it for pointing/waterproof then go for it. Might even be a price error thats y its so cheap so get it while you can

Nice find. Ordered one.

Not true.
>300mW of green with a ~2.0mm beam diameter at the aperture will be a great burner.

And maybe he wants it for a nice solid beam. It's not all about burning, you know.

dammit I really want one nao... that really frusterates me that I justa bought a 200mW greenie for the same price. D:

It looks like a good deal.
And the focus arrangement does not look like a problem, to me greens are for the pretty beam, not for burning.

Might have to order one. Been looking for brighter green.

I also care more about the beam than the burning.

I think I love the beam and burning equally, and although I haven't been into laser for very long time I would love to have a laser with a solid beam at night... how good is a 200mW green beam?

WOOW that is an amazing deal ugh only if i spent another 100 bucks i would of bought this but anyways that is a bargain

I have a $30 200mW(really 100mw) Focalprice unit that I really like and the beam is real nice at night. I also have a 200mW Rayfoss unit that is really bright and looks great at night too but I wish it had a thicker beam.

this got my interest!

i send a mail to o-like asking about the power and such, i hope its real then ill certainly buy 1.

the model number got my interest to Model: OL-532-300 seems to me that its a 300mw unit... o well ill just wait for a reply

Susie on mail: " We gurantee green laser >350mW "

awesome... Maybe I can ask for one for christmas.

did you ask if its ir filtered as shown on their site?

Did I/we miss something
My guess is that we get near 1W greenies for less than $400 before Christmas

i know what ill be begging for with christmas then, hope my gf has saved up some money she will be needing allot by then

off topic, since when did o_like start selling aixis modules? kinda cheap to 10pcs 20$


edit*
rayfoss seem to be selling the same laser for about the same price, only difference is they do state that its 300mW

I ordered it a few days ago. I should have this week because I got the DHL shipping. Susie said it will be at least 350mW. Ill put a review of it on youtube when I get it. Ill try to get some nice beam shots and some burning for the people who care about that stuff. My channel name is bulltex95, you can subscribe to know when i post the video or just keep checking back. I have one laser video on lasers and a ton of other crap. I don't have my techlasers 95mW anymore so I cant do a comparison of the two.

I've been watching this one for about a week as they were going throw web site trouble.
They have change the laser power offer back and forth from 350-400 no ir filter, to 300 with ir filter,
and now 350-400 with ir filter. I've been waiting for the site to settle down.
But now I will be at the bank monday to put money in to order one myself.
Don't you guys buy them all tonight

Wow, that's sweet make sure to let me know when a review of this thing is up

yus, save sum for christmas.

very nice host too. great find!

Hmmm, they also show a 500mW version that looks to be in the same host but that's $599!!!

I thought most of the modules over 200mW had to be those beefier ones that wouldn't fit in that host? Even the 300mW modules on O-like's site are $225. Freak 12mm modules perhaps? I hate to be sceptical about a trusted seller but it does seem to be a bit too good to be true doesn't it?

I really do look forward to the reviews on this though and hope they shut me right up!

I think it was Jetlaser that wrote something about switching from 12mm module to 30mm or so at around 200mW.
It appears that the 12mm and/or the crystals fitting in them cannot reliably handle more heat than that.

This is precisely my point Toke, I'm just not sure you're going to get a reliable 300mW output from those 12mm modules. You're also going to need a 5.6mm, 2W pump diode! Do 5.6mm diodes go up that far?

Just questioning really. As I said above, I'd love to be proved wrong.

I was the one who first brought up the power issues with the 12mm green modules.

Although the crystal sets are capable of handling more power (KTP has a much higher damage threshold) under the proper conditions (TEC stabilisation, proper heatsinking), these conditions are not present in the 12mm modules.

Damage to crystals in these modules is often caused by thermal stress as the tiny crystal set struggles to cope with the sudden expansion caused by the heat. There is not enough mass for the heat to be transferred from the crystals and into the surroundings.

There have also been several repeated cases of "sudden DPSS death" involving these high-powered 12mm modules. Upon closer examination all were caused by crystal set damage.

This is why in the larger 30mm modules sold by O-Like and used by JETLASERS have larger crystals, and independant YVO4 and KTP crystals. These modules also have independant optics to reduce the impact of thermal stress.

The larger modules are also pumped using C-Mount diodes which are screwed to the base of the module.

There's no way one of these larger modules will fit in that host. Someone pointed these new hosts out on LaserChat, but I didn't bring them up here because there'd be no way they would put out 400mW after IR filtering.

Although it is O-Like, and they do have a proven record for delivering on-spec lasers, I will remain skeptical until we get some reviews along with long-term updates to ensure there is not rapid degradation.

I'll be making an info thread about green modules soon, too.

@Morgan, the diodes that are used for pumping are special open-can 5.6mm diodes. These are often 300mW but there are 500mW versions available.

"Normal" 5.6mm canned diodes go up to 1W, however, these are usually off-spec by up to 10nm, which renders the diode useless for DPSS pumping.

CNI uses B-Mount diodes which are attached in a similar fashion to C-Mounts.
