> Dear Colleagues,
>
> 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 reading this overly long post and for your feedback.

> Cheers,
