Where is Mixedgas

[mixedgas]

Mixedgas is in the middle of fixing a room full of big optical tables with MEGABUCKS of gear.

Mommas, Don't let your babies grow up to use Femtosecond lasers... Very difficult to adjust and repair.

I spend most of my time adjusting a long Ti-Saph laser cavity with 9 mirrors and two intracavity prisms. A hour to drive to work, a twenty minute walk from parking to the office, 40 minutes for the pump laser to warm up, two hours to adjust and warm up the seed laser.... ETC

So I've been doing 12-14 hour days for the past two months trying to fix this system, deal with office politics, ordering parts, fix other systems, plus some volunteer work on a medical project to stay sane and meet people. femtosecond is not easy, I had to hire a specialist to come in and train me.


Optics chain ** is pump laser one, 8 watts of cw green, a IR femtosecond master oscillator, a IR regenerative amplifier/pulse compressor pumped by 35 watts of green*, a dual OPO and lots of specialized optics to handle and detect colliding ultrafast pulses.

I'm sorry if you needed me, but right now, survival and the commute are job one.

*No, the 35 watt DPSS q-switched shoebox will NOT be coming to SELEM. Merely lifting it off the optical table would set me back two weeks on adjusting the optics train... Which has over 140 mirror adjustments. That is when I stopped counting....

** Mira, Empower, Verdi, Topas, Spitfire, plus a Scanmate dye, a Infinity, a Vanguard, some HENEs, a Argon, some diode based raman systems, and a Antares. Yes, we still use cooling water...

Sounds excellent Steve, I can't think of anyone more suited for, or qualified for the job in hand.

Keep smiling

Shameful use of that much green laser power Steve

Seriously, seems a hell of an interesting job! Though I hardly imagine how weeks of laser alignment looks like...

So, in the end, what percentage of the time did the postive peaks of the two light levels hit the surface with the tops of the peaks within a 1 nanometer coincidence window of each other, within a 10 nanometer window?
As expected, much worse or much better?

Steve I will be sending you that mirror soon lets see how long it takes your system to vaporize it

I dont know yet. Still have no signal. Today's excuse is the climate control system went bonkers two days in a row. These lasers like to work at 70'F and less then 30% relative humidity, not 85'F and 45%, which is what we had until the repair folks got here this afternoon. If I even open the lids at 45% RH, I'm a fool, because the Ti_Saph crystals are cooled to well below room temp.

I do know this. I want a Verdi the next time I do laser shows or Holograpy . NICE laser.

Just ordered an 18W Verdi for the next system to build here!

Any luck with the aom?

New current limited bench supply arrived yesterday, from China, so I can fix it.
Its on my bedside table as a reminder for this weekend.

Why did you buy the Verdi? This is just as good and half the price. http://www.lighthousephotonics.com/

It is the guy that designed the Verdi.
