Hi there,

I was looking at multiple vendors' websites for an optical fiber wavelength
combiner (two or three colors), or what is called fused fiber WDM. I have
noticed that most of them are designed for low to medium power level
applications, e.g. up to 300 mW. I was wondering if anyone here has
experience on using these devices, e.g. what is the maximum power it can
take, or is there any high power version of it that can take up to 1 W of
CW in the visible. I am thinking of using it in a STED microscopy setup but
I think 300 mW power limit might be at the lower side for this application.

Thank you very much in advance,
Lu

Hi Lu,

I'm assuming this is single mode?  Putting 1 watt into a few square
microns can be fairly tricky, as the power density is gigantic.  What
wavelength are you using?  I've seen fiber faces blown apart by ~150
mW of 800 nm (femtosecond) ti:saph light.

My bet is that the coupler itself won't be much more vulnerable to
damage than the fiber its made of, but that you might have trouble
just getting that kind of power (depending on wavelength) into a fiber
without ablating the connectors or (depending on defects) your
splices.

Hi Mike,

Yes. It will be single moded. We have coupled few hundreds of mW of Ti:
sapphire laser at around 800 nm (CW though) into a single mode fiber
regularly without burning the fiber facet (we used bare fiber so that if
the fiber burnt, we cleave it and redo the coupling). I am not quite sure
what will be the case for pulse laser. I guess the damaging mechanism
sometimes varies from case to case. For the WDM, I think it might be the
fused coupler that may be vulnerable to damage but I could be completely
wrong about it. Will try to talk to some vendors tomorrow to figure it out.

Thanks,
Lu

Hi,

I know qioptiq has SM fibers for coupling up to 500mW in the visible range. They might have more options offline

Hi Julio,

Thanks for the information. I will try to reach them.

One more thing, when the fibre survives, you might disintegrate your sample...
