607nm 170mW kvant Lab Laser
Yes. PURE Orange.
It all started here...
...Yup.
The color:
The best way I can descibe it is juicy. This is a very saturated orange color with no bleeding into red or yellow. Pure. Orange. I will say however those of us with 589's can play around with some 532's and 520's for a while. If the 589 looks pretty orange after a while of that, it's pretty close to the 607's color. Just not as "juicy".
About this head:
This is a 170mW head from kvant. They are advertised at 180mW but the lead time on this was so long (2+ months) that I just accepted the 10mW underspec they came up with and asked them to send it as-is.
607nm itself is generated through DPSS that is a little unusual compared to what we normally see. Instead of a process our 532's use of 808 -> 1064 -> 532, this uses a different pump wavelength and has a transition directly at 607nm. In this case, this crystal wants a ~445nm pump wavelength, and you can even see some of it leaking through on the right, and additionally some of the other transitions peek through a little bit with that greenish spot on the left being the only one I could picture.
As measured by kvant from the factory, this has a 0.76 mRad divergence. I measured 0.8 without any sort of good equipment. It's nice to receive these QA checks along with the head.
The beam shape starts in TEM00, then goes up in power and hops to a shape resembling the asterisk symbol (*)
However... there is only TEC stabilization on the internal optics for cooling. There is no fan... so I will need to piece together my own cooling solution. I have something in mind, I just need to build it first... I'll give an update when I get that put together. On a flat metal surface (all the pics in this post) it has about 10 minutes of run time that I'm comfortable with. Without any heat spread, it's only about a minute on that I would subject it to.
How it stacks up against 589nm and 635nm:
So since I bought this... does that mean 607nm lasers are coming down in price anytime soon? No. Any chance of handhelds? No. CNI says that cannot be done since the optics they need to get any appreciable amount of light are too big. I didn't check with kvant, however I waited 2 months for them to build this head in their standard size. Who knows how long it would take to produce one small enough for a handheld, if they even could at all.
And I'll end it with a link to the album and a dump of a couple more pics. I add to these albums every now and again so there's always more to go around.
Thanks for checking this out! This is my new all-time favorite laser.
