> Do you own/you want to buy a two photon laser from Spectra Physics/Newport?
> I would like to share my experience with the Spectra Physics/Newport
> service :
>
> 15.03.2011 Our MaiTai laser has a very low output power and doesn't
> pulse. I contact the service engineer.
>
> 29.03.2011 After two weeks of mail exchange with the engineer trying
> to solve the problem in remote, it turns out that this is something
> more serious. The engineer comes over, collects the laser and
> promise we will have the laser back in 1,5-2 months. End of May
> then. That is the only Multi Photon laser in the facility and I
> start already to have worried users around asking when the laser
> will be back.
>
> 03.06.2011 I write Spectra Physics (SP) urging news about the laser.
>
> 27.06.2011 SP informs me that they will start to work on the laser
> "this week" and the laser should be back in the week of the 11th of
> July. They added "If it is possible to do it any earlier we will".
>
> 01.07.2011 SP informs me that there are good news: the laser will be
> really back by the middle of July.
>
> 14.07.2011 No news from SP. I write them asking about an update. SP
> answers quickly: new installation date, the 3rd of August. 2011? My
> bad, I forgot to ask them.
>
> 05.08.2011 Again no news and no laser back. I write this time the
> Sales Director a complaint letter asking when we will have our laser
> back and if it is possible to have a replacement instrument, as we
> are without laser since more than 4 months now.
>
> 17.08.2011 Receiving no answer from the Sales Director I call him,
> and receive assurance that the laser will be back next week.
>
> 26.08.2011 Still nothing. I write a new complaint mail to the Sales
> Director. He answers that there were more delays, but by the 31st of
> August he will surely be able to know more about when the laser will
> be back and he will contact me.
>
> 01.09.2011 No news from SP (to be continued).
>
> Now it might well be that all of it is absolutely normal, I just
> would like to get a feedback from the community if there is
> anything else I can do in order to have the laser back. Thanks for
