Smile New 4 Watt Blue Laser

Hi guys and gals,

Just received my 4 Watt blue laser from Hong Kong (a company called HoCo (HK) Technology Limited). This was a laser costing approximately $256 US or £156 GBP. Have checked it out and it is truely awesome. Compared to my green 100mW laser where you cannot see the beam in daylight, you certainly can with the blue laser.

Default Re: New 4 Watt Blue Laser

Don't think you can get a true 4W with $256 though, most likely 1W which mean you get marked a lot. I suggest you to send it back and get your refund if that's possible.

Any links?

You could send it to a member here and have it LPM'd. I know it's hard to trust your baby with a stranger, but we're friendly.

Tried a Google search for your laser but no joy, have you a link? I doubt you've got a true 4W unit but will reserve judgement until there's some more info Nonetheless glad you're pleased with your purchase, post some pics!

Default Re: New 4 Watt Blue Laser

Thanks people for your posts.

Correct me if I am wrong, but I can imagine that this laser will not be 4 Watts beam power, but 4 Watts power consumption. I base this hypothesis on the fact that the visible beam would account for a small portion of the total power required to lase, the remainder being dissipated in heat and unwanted IR wavelengths. Furthermore, I am sure that if the beam power is 4 Watts as advertised, this will only occur if the batteries are fully charged. Once the laser is on, due to a high power consumption, the output beam power would decrease quite quickly. Much would depend on the minimum power required to lase as to when the laser would not operate.

This I am happy with!

What I do find perplexing with is some Chinese manufacturers claiming 40 Watt (or higher) handheld lasers which does not make sense as the batteries they are use are not capable of producing that kind of power.

Any thoughts?

TGL is right, only DPSS lasers (and perhaps a few gas lasers with the correct broadband optics) emit IR. They work on a whole different concept where the IR is turned into visible wavelengths. You have just a straight up diode laser. No IR to worry about.

Default Re: New 4 Watt Blue Laser

must be a real big host if it could be a true 4w laser i really doubt it, even a 1w laser will be crazy bright even in daylight i think u got ripped off judging by the name and what google shows it says nothing about lasers so it looks weird.
hm google the name shows its some kind of export mobile fashion company ? lol.. wtf.... dont see anything about lasers under that name but what do i know..


Hoco Technology (Hongkong) Co., Ltd. was set up in Honkong and our main business is supplying telephone and PC accessories and OEM and ODM services.

Default Re: New 4 Watt Blue Laser

Ah well, I have a blue laser that is considerably more powerful than my green laser!

To tell you the truth, I am pleased that it probably isn't 4 watts as that is a stupid amount of energy packed into such a narrow beam. As a motorcycle instructor, I have a huge responsibility towards my students and their safety - but to have a hand held laser of dubious wattage scares the living daylights out of me!!!

Anybody in the UK know where I can get it measured?
