Succesful The ½ km fiber did not arrived in time for this meeting, but ……. The physics and the technology of each optics inside the laser The subtle connections between the optics and the mode-locked physics of the laserĦ Next on the laser A play for the best trade-off between the pulse length and the pulse energy The implementation of the SESAM technolgy for a real reduction of the pulse length Two weeks ago the laser reached the Project features 100 ps pulse length Amplitude and time stability (few %) 100 MHz operation 2 W output power (20 nJ/pulse) For lower power and wider pulse duration ranges, Multi-Shot scanning versions are available (MS-ROC).ģ Those values give an order of magnitude for a 1030 nm laser.Presentation on theme: 'LAB-LASER MILANO Pulse shaping Sparc meeting october 4th 2004.'- Presentation transcript:ġ LAB-LASER MILANO Pulse shaping Sparc meeting october 4th 2004Ģ OUTLINE Nd:YAG laser state Laser-fiber coupling Pulse “deformation” in BBO crystal Improved shaper designģ 1- Laser as tool for pulse shaping tests Up to 125 kHz laser repetition rate (with Trigger and Enhanced Detection options, or 18 kHz without)ġ Effective spectral bandwidth to be defined within the accessible spectral range according to customer's requirementsĢ The measurements are averaged over several pulses for laser with repetition rate higher than 62.5 kHz (with Enhanced Detection option).
