Difference OPSL and DPSS

[mccarrot]

Can someone tell me the technical difference between OPSL (Optically Pumped Semiconductor Lasers) and DPSS ('Diode-Pumped Solid-State) lasers?

thanks.

I think OPSL would refer to lasers like ruby, dye lasers etc, which just use a regular, non-coherent light source to pump them, whereas DPSS is pumped with 808nm coherent light from a laser diode.

That's an article that explains OPS lasers. Refer to Wikipedia or other sources for explanation of DPSS lasers.

Bedankt voor de link Jeroen.

If inderstand correct, OPS Lasers got better beamspecs, are smaller, longer lifetime, higer power, and can create more colors.

Does someone got some pricing on this OPS lasers?

Ask Hugo (or send an e-mail to Light-line.de , that company is the certified Coherent system integrator which supplies Hugo.. You can't buy them direct from Coherent, the driver/TEC has to be made by the system integrator).

Don't fall over backwards when you hear the price

Can you give us an idea of the price? I'm curious, but not curious enough to write a mail...

As for the difference between OPSL and DPSSL, it's mainly that in DPSS you pump (excite) lanthanide ions in a glass matrix to get them to lase at a higher wavelength. In the case of OPSL you pump a carefully engineered semiconductor instead.

OPSL is more flexible, as it's easier to change the emission spectrum of a semiconductor and their absorption is much wider. A simplified picture is to think of it as a solar cell and laser diode in the same package.

Technically it's more like a solar cell and a quantum dot laser in the same package. Quantum wells are cool.

Those SDL MOPA lasers are OPSL correct? I got one that daedal is trying to see if it works.

mopa is master oscillator power amplifier.

So you have a little red diode with nice beam quality, because you can get good beam quality in a small weak diode that you can not get with high power. Then you have a second diode die that is the power amplifer. The beam from the nice quality diode goes into the power amplifier, in your case does a single pass through and comes out with a lot, lot more power. Its a expensive way of solving the red problem. With the issue of having to make the dies track each other in wavelength across a wide range of temperatures.
