What is the optimal solution now?

[MorgothV8]

Hi, I've created 2 other threads related to my laser research and now I just wanted to get some feedback about what is the optimal solution to those requirements:
- IR laser in 860nm - 1150 nm range (this is the range that given laser must conform to).
- Can run on 110-220V (so I can use portable batteries/power banks used for emergency car starting) and must be able to take it outside, so not a big bulky system weighting more than 10 kg.

Then in the following order of importance:
- Smallest possible divergence (minimize divergence).
- Maximum power (5-10 watts minimum, but I saw even 45W ones, I would love even 100W). Maximize power.
- Minimum price (certainly not 5 digits USD, ideally below $2k, extreme end about $3.5k).

Can anyone suggest anything?

I've found multiple hits (I'm not specifying any of them on purpose) of laser modules 980nm with 10W power but very disappointing divergencies of 5 mrad or 3 mrad - even for then I don't know if they're fake or not....

There exist ~960nm 10W fiber coupled pump diodes for Yb:fiber laser. You can get broken laser with a few pump modules for <$500. Then you need some nice driver, big heatisnk and collimator

What is the purpose of this device you wish to build ?

Have a look here and pick something that exists for your daydreamed dangerous device that does not exist and is likely to be illegal to use other than alone by yourself in your basement if it ever does exist.

if you want a DPSS laser have a look here concerning price of CNI DPSS lasers see:

Thanks for all feedback, I really appreciate this, I'll check all options listed, possibly reconsider parameters or price a bit, I may ask once more when i figure out something that would look promising for me.
As usual, thanks for all feedback.
