Thanks for the information Anthony P. Good to know it’s laser then driver then power. its easy to pick up lasers but some are without a driver and the few I’ve bought with a driver have no paperwork with them so it’s a pure guess what Amps to use if I can’t find data sheets. These lasers have...

And if I can’t find a diodes Data sheet ? Can I start with low A and move up ? And is this adequate as a bench supply ?

Thank you, that s very generous information. As a newbie it’s all completely new to me but I’m keen to learn and contact people.

Thanks for that Mosc007, I’ll definately follow those leads. Is there a desktop power supply that’s will cover lasers ? I didn’t want to buy the $19 version only to buy a more professional version 2 weeks later. I’m testing from 1mW to 1000mW and is there a chart for what Amps for what mW and 12...

Does anyone in Australia have my lasers to sell please ? We have rather draconian laws here and I didn’t wish to run afoul of the law by purchasing overpowered items from overseas. Id like to do some optics experiments for parties and general nerdiness as well as look at setting up a laser...

ZRaffleticket, that’s great information. Thank you.

I take it that the higher the nm the greater the penetration ? Or maybe not ?

Thanks Julian, there’s my starting point. Most appreciated, Brett.

Yes Julianthedragon, that’s it. The volume of fractures every hospital does just on hands and feet is phenomenal, we can tie up 8 permanent staff in a theatre doing hand fractures all day. Probably 100 man hours if you add in the specialists and it’s mainly on broken fingers, lacerations or...

Brilliant, just what I was looking for.

I’ve worked in operating theatres for +20 years and the most time consuming, confusing, problematic, expensive, dangerous, resource wasteful process is X-ray. And the results aren’t that terrific. During Surgery, everything has to stop while we assemble the radiographer, everyone dons lead gowns...

That’s great RedCowboy, I thought it would be possible to refocus but you never know with lasers if there’s a reason why not. Thank you.

Is it possible to focus/ refocus the beam with an exterior set of lenses ?

Thanks for all your replies folks. Im researching what frequencies are able to penetrate a limb and could particular frequencies be more sensitive to vascular structures or bone, metal implants, and what else could be uncovered by working through the frequencies and their variables. So casting...

Newbie here but looking to learn. I see there are many frequencies available but is it possible to have one laser and many frequencies through adapters? How can you multiply or divide the frequency and create many nm variations from a single light source ? I’ve got to do some research into a...
