Default FS 800mw 980nm Laserbtb HL

$120 shipped. Conus. This is great for experiments.

For sale is a H980L-800B laser. It's from Laserbtb. I don't have an LPM but the rated power is 800mw. It can burn dark objects, even leaves when focused. Leather can be burned from a foot or two away when unfocused. Goggles really are necessary. It comes with a little plug dongle and a metal pin. The plug dongle can be cut so the laser can be turned on from a distance with another switch. It comes with two metal keys. It has a shutter and adjustable focus. It is very sturdy. It comes uses one 16340 battery.
Doesn't come with IR indicator card. If I find it I'll throw it in. You need goggles that can block this wavelength.



Pros:
Laser burns dark colored objects well
Laser has lots of safety features
Runs a while on batteries
Has a long duty cycle
Pinpoint focusable





I dont have a power meter available but its specd at 800mw. Here are the factory specs:
Wavelength (nm) 980
Beam Colour infrared
Transverse mode TE
Range in darkness (m) 300-500
M2 factor <1.2
Beam divergence,full angle (mrad) <6.0
Beam Diameter at Aperture (mm) <2.5
Spectral Linewidth (nm) <0.1
Polarization Ratio >100:1
Warm-up Time (minutes) <0.5
Operation Temperature (℃) 10~30
Storage Temperture(℃) -10~+50
Expected Lifetime (hours) 5000
Laser Head Dimensions(DL, mm) Φ23.5 * 180
Cooling System metal heatsink
Operating voltage(VDC) 1*16340 battery
Warranty time 6 months

Not interested in buying, but didn't you just buy this laser very recently? Maybe I'm going crazy?

Yeah I did but I don't use it! What a waste! Maybe someone who wants to experiment can buy it off me. Oh well. I'm really going for that jetlasers 473 30mw!

$115 shipped conus. This would be great for some DPSS experiments I assume.

All of the DPSS lasers we use are pumped by 808nm, not 980nm. Can't just fire random IR wavelengths into a crystal and have it work. Even then, you don't want a pointer for that sort of thing.

Good luck with the sale though!

How do they design crystals for such a specific wavelength. We're talking a few billionths of a meter lol.

Is 980nm direct diode, or some kind of DPSS IR wavelength?

Direct diode, at least in this case.
