Multi-mode diodes are incompatible with optical media. The focal point is far too large.

Default Re: Sanyo develops laser diode for 12x burning

Isn't that mostly a matter of a microlens with a blazed grating or somesuch?

The DHT-0811 certainly doesn't operate in a single mode, and has a blazed grating mounted in front of it.

Google "external cavity diode laser" or somesuch... I have 12-pin reds in a very odd case, with a microlens instead of the window, having two mirrors and one blazed grating inside the microlens, and having a TEC between the laser chip and the header plate, as well as something that looks like a very advanced APC with some logic, a photodiode and some sort of H-bridge, going by my microscope.

I love getting all the returns at the local home electronics outlet.

I'll take 350mw of red and raise you a 200mw bluray.
Same here, I remember when we would buy those ps3 sleds off of eBay for like $60 a piece for 10mW of blu-ray, and it was pretty special for somebody to have one of those. I think there is a thread a year old somewhere where somebody made a topic asking about blu-ray burners, and half the thread is everybody dreaming of 125mW of violet. ;D I can see in a couple of years when it will be outdated to have a 200mW red burner because the violets will be so powerful that it will be useless to keep a red around for burning. ;D
