Re: new to laser tech and have a unique question
With a widened ed beam power will drop off and I believe it's not linear as in 2x the size 1/2 the power. The only laser that could do something like that would be a c02 laser as you need more than a few watts to do what you're attempting. Trouble is regular glass blocks the Co2 WL 10,600nm. You'd have to aim it right over the open container. Also you need to know variables such as the liquids boiling point and such and such.

Re: new to laser tech and have a unique question
Man I can't help you much more here , but if a CO2 laser is needed I just want to let you know you they need special optics that look opaque to you.
I feel like an idoit though I forgot to ask you , what volume of liquid are we talking about , are you allowed to die it?
if it's a rather small amount you might be able to get away with a few watts of 445 provided you can die it orange.

Re: new to laser tech and have a unique question
The highest you can get from 1 diode at 445nm with proper optics is 6 watts if you're lucky.
They are rated for 3.5 watts normally and have worse specs beam wise
All 445nms ~200mw (0.2watts) and up are muilmode diodes and so will not focus as well a single mode dioide.
The 7.3 in the video are 3 combined lasers into one beam.

Re: new to laser tech and have a unique question
What is the material's thermal capacity? What color is it? Is it translucent? How much of it is there? Could you get us a picture?
I can tell you what kind of laser you need if you can answer all/most of these.

Re: new to laser tech and have a unique question
Well honestly if you want "instant" you're going to need a Q-Switched laser. Do you have any idea what the thermal capacity of the material is?

Re: new to laser tech and have a unique question
Not really possible to have it "instant" with those kinds of restrictions. If you can forgo the "instant" part then it might be possible, but I'd need a time frame in which the material will be heated.
also keep in mind different WLs interact differently with different materials, so do you need it heated evenly or can it just be heated in one spot?

Re: new to laser tech and have a unique question
it would need to reach its max temp within a couple of seconds so it does not have to be instant but pretty quick. This fluid will actually start to evaporate at 400+ and that is what the sensor picks up. As the fluid degrades it evaporates at a higher temp.
The fluid has the viscosity of glycerin, is room temperature and when the machine is running the fluid actually warms up to 80+ degrees.
I would say it would be best to uniformly heat a surface area of an 8mm diameter circle. a rather small area. the more surface area the better. there is a sensor tube of corts situated above.

Re: new to laser tech and have a unique question
Okay, so do you need the laser to heat the ceramic, which then in turn heats the fluid, or do you need to heat the fluid directly?

Re: new to laser tech and have a unique question
So it's just thermodynamics. Since I cannot actually see the setup you have it will just be easier if you do the calculations.
If you want it heated evenly it's going to be harder to do. You're going to want a visible WL and have it resonate inside the liquid, allowing it to heat evenly. This will of course up the time it takes to heat, and the complexity of the device. Due to the heat capacity of said liquid you're probably going to need a pretty high powered laser.
I'm not sure a laser is the best option here.
