5W 445nm labby from OdicForce: did anyone try it?

[Devil_Master]

This laser: 5W 450nm Blue Focusing Laser Module (12V) with TTL Driver - OdicForce

- I noticed the title says 5W, but the description mentions "4+W". So, has anyone measured its actual power with a meter?
- What are the dimensions of the driver? The picture only gives the dimensions of the laser head.
- The description says "normally on full power": does it mean it activates as soon as you connect its power supply to the electrical outlet?
- Can the driver be immediately connected to this kind of power supply? UK DC 12V 2A Power Supply Adapter 100-240V Input, 5.5mm x 2.1mm Connector - OdicForce From the pictures, I'd say "no", because it looks like the driver has just two loose wires you need to attach to a suitable connector, but I thought I'd ask just to be sure.

May need to apply 5V modulation signal as well as 12VDC power to get it to turn on.

You'd need to splice the cable on that wall plug, or use the adapter they have: DC Adaptor (Socket) 2.1mm Pin 5.5mm Diameter - OdicForce

Can't comment on power output.

The Laser should NOT come 'ON' if the TTL
input has 0VDC on it. It should come fully
'ON' when the TTL input has 5V on it.

That is if you apply the 12VDC to power the
Laser. The TTL input acts as a very fast
'ON/OFF' switch.

You can roughly guess the dimensions of the
Driver by knowing the dimensions of the Laser
housing.

As diachi said.. we would need to have the
Laser in hand to tests it's power.

/googles "TTL"...
Aha, so that's what TTL is for. Okay, so the effective power of the laser would be the maximum power times the TTL duty cycle. Makes sense.

Do you think the circuit I attached would make a good power supply for that laser (in case I just want to run it at full power)? I already located components that are able to provide the necessary current.
Battery
7812 voltage regulator
7805 voltage regulator

...Why is the 7812 in there? It can't provide enough current. They're rated at 1A continuous, half the current that the driver spec says it needs. Even then, it's a very inefficient way to provide power. You'd need a decent heatsink on it even at 1A continuous.

Replace the 15V supply with a 12V switchmode supply (capable of >2A, I'd aim for 3A so you have some headroom) and then keep the 7805 to provide 5V for the TTL. TTL is high impedance, so you could even use a smaller regulator, although 7805s are cheap and easy to find.

Simpler yet, you could use a simple voltage divider to provide 5V from the 12V power supply, that'd be fine assuming the supply is decently well regulated.

But I filtered components for maximum output current, I selected 2.2A and the results showed that component...

Would it work, though? If this is the voltage divider, then adding a load between Vout and ground would be akin to connecting another resistor in parallel to R2, so the actual voltage would depend on the internal resistance of the load.

Check the datasheet, that's the peak current rating. You also need to take into account power dissipation for that specific package [(Vin-Vout)*Iout]. You'd also be better with a TO-220 package rather than a DPAK, just for ease of mounting/heatsinking/connecting.

Really though, there's no reason to use a 15V supply and a 12V regulator in the first place, just use a 12V supply. :thinking:

The simple and more rational choice is to ask OdicForce your questions-they will be happy to answer any and all.

I bought a laser from them in 2014. Before buying it, I had emailed them with various questions, but they never answered. Thus, I mentally filed them under "quick to ship products, but they won't answer questions".

S0 why did you buy it with no questions answered?

I don't understand your questions that after 3 years you can't comprehend, try, or get answers to.
Do you actually have the unit and power adaptor or are you just playing a game for attention?
All of your questions are as if you do not already own the product much less for 3 years nor have any common sense understanding of the product description on the web page?

They are not real questions -most of your questions are answered on the web page:
"This module has adjustable focus and optional TTL switching that can be used to control the power output (normally on full power, the TTL signal can be used to reduce the output power using PWM). 12V operation"
As for powering it -- it says you can use that 12V 2A Adaptor will power it so you buy also the DC Adaptor (Socket) 2.1mm Pin 5.5mm Diameter£1.25" also to be able connect it to the wires from the driver OR you can connect it to any other 12 2A or greater power source you want. The size of the driver? I assume in 3 years you could bother to measure the one you say you have---makes no sense at all.
PS the web page says 5000mW not 4+W

I assume the product came with instructions
In any case, Jonathan Swift has been responsive to other members recently--maybe give him another try by email or call him if you have any REAL questions that you can't answer easily yourself like the ones posted in the OP.

No, what I bought in 2014 was a 1W handheld laser, which now isn't being sold anymore (EDIT: this one). I wrote I bought a laser from them, not this laser.
My questions about that laser were about temperature and battery capacity, but then I decided that I could find out the answers by myself, so I took a risk and bought the laser. Yes, that laser came with instructions, which actually answered my questions (and the laser was a really fine product), but that doesn't help me with the labby this thread is about (and which wasn't even sold in 2014).
My confusion about TTL was due to reading a page of an unrelated labby sold by O-Like that claimed that the absence of a TTL signal caused the laser to work at full power.
(EDIT #2: there's even a driver sold by OdicForce that works like that: "This driver has optional TTL modulation: The output is on when the TTL modulation connector is floating ( not connected). The output is off when 0V is supplied to the TTL modulation connector and on when a TTL signal (5V) is supplied.")

I hope this cleared any possible misunderstanding.

OK clears some confusion---they are known for reasonable product. ---sounds like you have all the answers you need--if not contact them ---am reasonably certain they will answer--or call Jonathan and discuss anything not clear

Good luck

It does not say what diode is in it, just that it's a N--- company diode.
