This is the kind of really important and nice information to have before making choices, thank you so much for sharing!!!! I think this is not so long, I feel you were pushing your frustration back into the cage to make this so straight forward. I would like to ask what is the worked hours for this device before failure?, once again thank you

> 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.
