Re: 583.8nm and 589nm, the golden brothers

Bought a 3x3x5 KTP for 594.3, according to the seller. Now to figure out how to drive it to produce yellow, help? The wavelength is a bit different.

You need a Nd:YVO4 crystal coated for both 1064nm and 1342nm. Then pump with a 808 like normal.

Oh that would be great, very straight forward that way, except for oven.

Re: 583.8nm and 589nm, the golden brothers

It should be straight forward. Will just take careful phase matching, and expect a low efficiency. The crystal is labelled 594.3 nm, but 1064+1319 is actually 593.5 nm. The crystal coatings won't be too specific, so should have no problems getting output once orientated correctly.

Re: 583.8nm and 589nm, the golden brothers

No, 1319 is for the 589's. And would then involve a Nd:YAG rather than Nd:YVO4. And the coatings on the crystals probably wouldn't allow that wide a range of IR.

Re: 583.8nm and 589nm, the golden brothers

Found this on ebay, now to figure out a way to put an oven in it for my yellow coherent 3x3x5mm KTP and room for a YVO4 crystal. I found a 4 watt wavelength locked 808nm C-Mount laser diode cheap, so I won't have to mess around with a TEC for the diode. This already has an unknown KTP in it where the white tape is.

Backup plan is to just use this for a 532nm green KTP, if it doesn't work out for the yellow crystal.

I've never seen a something so elaborate, but I like it.
You should be able to use it for your yellow. But it may be worth using it for a high quality green instead.

Re: 583.8nm and 589nm, the golden brothers

For green, I have two of the 4 watt rated wavelength locked 808nm C-Mount diodes I could PBS combine to drive a crystal harder and produce a lot of green, don't know how stable it will be in this kind of frame unless I find a way to control the temperature of the crystal holder, or perhaps the whole thing inside a temperature controlled aluminum tube. I think this is one of the most awesome things I've seen for a home built DPSS project, well, sort of home built, most of the work is done if using this.
