2 Agenda Overview of the Synchronization System at FLASH Requirements for the Master Laser Oscillator (MLO) 3 Generations of MLOs RF Lock to Master Oscillator Measurements Pitfalls Conclusion 2

6 Requirements for the Master Laser Oscillator Mode-Locked Erbium Doped Fiber Laser Pulse Duration <100fs (FWHM) Repetition Rate MHz Output Power >120mW Integrated Timing Jitter <10fs [10Hz 40MHz] Amplitude Noise <2 x 10-4 [10Hz 1MHz] Reliability / Redundancy 6
7 1st Generation MLO (Breadboard Version) Original design: J. Chen et. al., Opt. Lett. 32, (2007) F. Löhl 7
8 2nd Generation MLO F. Löhl 8
9 2nd Generation MLO 9 F. Löhl Temp. Stabilization Controller included Variable Set point Stable Ground Plate Distribution included RF Electronic included Motorized Wave Plates
10 3nd Generation MLO A. Winter 10
11 3rd Generation MLO Compact Modular Parts Lower Costs Online Spectrometer A. Winter 11
12 MLO Included Features Overview 1st Generation 2nd Generation 12 3rd Generation Piezo Motorized Translation Stage Optical Monitor Output Electrical Monitor Output Temperature Stabilization Motorized Wave Plates Modular Parts RF Lock Electronic Online Spectrometer
13 RF Lock to Master Oscillator M. Felber 13
14 Measurements Noise and Jitter Integrated timing jitter: < 6 fs [10kHz 40 MHz] F. Löhl relative intensity noise: % [10 Hz 1MHz] 14
15 Measurements Spectrum and Pulse Shape (I) For different Pump Laser Power Level Wave Plates optimized for maximum Output Power Similar Spectra / Shapes are Achievable F. Löhl 15
16 Measurements Spectrum and Shape (II) For different Wave Plate Settings Constant Pump Laser Power of around 890mW F. Löhl 16
17 Measurements Autocorrelation Different Wave Plate Settings Constant Pump Laser Power Pulse Width: fs [FWHM] (depending on Configuration) F. Löhl Different Output Power 17
18 Measurements Amplitude Stabilization Without Feedback J. Zemella With Feedback 18
19 Pitfalls Piezo bends due to weight / torque Alignment Make every Parts removable from the top Have enough degrees of Freedom Make the Ground Plate thick / stable enough A Modular Design could cause alignment problems Put the Shutter not before the RF Lock Monitor Port 19
20 Conclusion The MLO has a strong influence on the complete system Wave plate and pump power settings influence the optical spectrum A high precision diagnostic is needed to investigate the impacts In contrast to stretched pulse lasers, to achieve modelocking wave plate settings have to be changed Different wave plate settings for minimum phase noise and maximum output power Questionable whether two identical MLOs could be set up such that switching has no impact 20
