To Femtolase, about the DAZZLER

Original:

Dear Pascal:

We make sure that we need WB-800 T1 Dazzler, and the foundation is OK. There are some questions about delivery, operation and training. The first question is when do you send the Dazzler and training time. Do we need prepare laser systems such as 8-pass amplifier, stretcher and compressor for training or you could take your arrangement here for testing and training as training?

The second question is on our laser system. We use a 12 nm FWHM laser for testing and building up, but we have to use a 37 nm FWHM laser in main experiment. Would this type Dazzler work efficiently in 12 nm FWHM laser?

The third question is about the system energy. Because our testing system is building up, such that laser beam energy may not enough. Would you please tell me the minima energy need? Indeed this question is depending on the first question.

Dear Pascal:

We are sure now that what we need is the WB-800/T1 Dazzler, and there is no problem about the budget any more. However, there are some questions relevant to the schedule of delivery, installation, and training. Although we have a 10-TW laser system that uses a 40-nm FWHM oscillator, we do not want to do the test and training on that system because it will take the system off-line and delay the schedule of the experiments. However, we have another laser system that contains a 10-nm-FWHM oscillator, a pulse selector (running at 10 Hz), a stretcher, and a compressor. We are currently constructing an 8-pass amplifier to put into that system. Therefore, the question is what kind of system do you need here for the test and training of the Dazzler? Can it be tested using a 10-nm oscillator? Does it need the 8-pass amplifier to booster up the pulse energy in order to test it? That is, what is the pulse energy level you need? Furthermore, what kind of waveform measurement do we have to prepare for you? Or, will you bring diagnostic equipment with you?

If you need the oscillator bandwidth to be >40nm, then we will have to wait for the upgrade of the 10-nm oscillator to 12-fs oscillator (which might take half a year). In other words, we need to arrange the proper sequence of (1) constructing the 8-pass amplifier, (2) test the Dazzler, and (3) installing the new 12-fs oscillator. Of course, there is another solution to this. We can get the Dazzler now, and ask you to come here at a later time when the system reaches the status you need for test and training.
