What kind of laser diode does "ODIN" 808nm 3 Watt laser pointer use?

[rajhlinux]

Hello, I would like to get an idea if I can make an 808nm 3 watt laser myself or is it just better off simply buying one from Odin:

Here is their laser 3watt 808nm laser pointer link to get an idea:

"ODIN" Infrared (IR) Laser 808nm - 980nm - 1064nm

The ODIN high power IR handheld laser is available in three frequencies 808nm, 9890nm, and 1064nm and is available from 500mW to 3,000mW.

biglasers.com

Can anyone explain how the "Odin" 808nm 3 Watt pointers works?
Which laser diodes are they using?
How is it able to produce 3 watts of optical power?
I would like to understand why is it worth $700 (before tax and shipping) and is it simply better to buy from them or I can rather DIY.

Thanks for any info.

Stay away from reseller Biglasers--they do not make any lasers, just rename manufacturers products, and overcharge for everything they do have and don't have.

Jetlasers is not a reseller they are the manufacturers of the laser pointers they sell
They make and sell a range of IR laser pointers at 50% of the price Big nothing is charging.
Jetlasers 1 piece retail prices for IR laser pointers are $199 to $399.

Even the 5 watt 808nm diode is just $86.12.
