Exclamation Mitsubishi LPC-826

Anyone know if the Mitsubishi LPC-826 laser diode is single mode?

The LPC-840 has higher output and is SM too.:

The LPC-840 is reported to be a variant of the ML101u29 with a higher output rating. This has not been confirmed and the divergence of this device might not be the same.

Great burner diode. Built a LOT of them. Never tried an 840. Could have s2orn I read that people had issues with the 840 somewhere. Easy to get the 836 cheap in the states or overseas.

That's a good thing ... a Gaussian beam is the perfect single mode beam.



Gaussian on the left. The right image is a top-hat beam profile.

The LPC-826 isn't perfectly Gaussian, but it's pretty decent for a diode.

It does have the wings, but they make up a tiny fraction of the output power.

Default Re: Mitsubishi LPC-826

That woudl be quite funky indeed

But in general: Any laser diode that reads or writes an optical disk (cd, dvd, bluray) will be single mode. There is no way to collimate the light of a multimode laser onto a disc to read or write pits that are not much larger than the wavelength.

The 'wings' are a visible artifact, but these is very little power in those, and it does not cause any problems in it's intended use (like accidentily erasing a track next to the one you are writing etc).

A perfect single mode diode should have a perfect gaussian output profile, but there is some room for tolerance in practical optical drives. There is also some room for error in wavelength, as most people would expect something like a dvd player to work over a reasonable range of ambient temperatures. When things heat up the discs expand and the wavelength gets longer, but not at equal rates.

I was considering purchasing this 3 pack. I recieved an LPC 826 from Flaminpyro but I think I popped it with a Nano Drive v6 (500ma default I believe) is there an odd pinout to these? My plan was to put it in a 22mm 510 dtr heatsink but never got that far. Can I wire these up like a typical diode with the drivers negative input wedged between the module and heatsink or does this diode require the module to be isolated. I will be using a flex drive from Jordan.

I did successfully put together a GGW Red LCC .and a PHR 803T in 22mm 510 heatsinks and they don't seem to require any special wiring or module isolation.

Default Re: Mitsubishi LPC-826

I'm not sure what you'd call an "odd pinout", but with these diodes the case is connected to the cathode. With the typical 445 nm the case is isolated completely.

So if you have a driver that does current sensing on the negative/low side you cannot use these diodes when electrically connected to the battery negative through the case. This low side sensing is often employed in switchmode drivers so beware!

I'm not sure what you'd call an "odd pinout", but with these diodes the case is connected to the cathode. With the typical 445 nm the case is isolated completely.

So if you have a driver that does current sensing on the negative/low side you cannot use these diodes when electrically connected to the battery negative through the case. This low side sensing is often employed in switchmode drivers so beware!
I was going to use the flexdrive in a negative host. I don't fully understand what your saying but is this setup going to work? I'm not even sure what to start researching to grasp the flex drive.

Default Re: Mitsubishi LPC-826

It is my belief while some LPC826 diodes can take 500mA and live some can not, and that is why I never run them much past 400mA drive current.

I like the GGW red myself they are also single mode and seem to be a bit hardier, I'll have to put some of both to the test and record the results.

Good luck have fun be safe

I would be able to tell if you had a circuit diagram for that drive, or a link describing it in detail.

There have been so many drivers by so many names over time i cannot really tell without looking at the exact one you are planning to use.

Afaik the 826/836/840 diodes all have identical pinout so it doesn't matter which one you choose, apart from setting the driver to the correct current.

Thanks for the reply. I think I have it. The circuit runs batt positive to driver in positive, driver out positive to diode positive, diode can to module to host to batt negative. Neither driver negatives wired. One pin on diode (+) wired up. I haven't soldered the jumpers on yet so not 100% sure. Once I put the driver into the next output range I'll feel more confident.
