Tender Details

This call for tender concerns the acquisition of two laser systems for cooling Rubidium. System 1 (repumper): Laser emitting at 780.24 nm on the D2 line of Rubidium with the following characteristics: - Useful power at fiber output minimum of 25 mW at the nominal wavelength (50 mW would be appreciated) - Line width (linewidth) of the free laser less than 100 kHz at 1 ms - Isolation stage of at least 30 dB - Fiber output, FC/APC connector, with a single-mode fiber maintaining polarization of length greater than 1.5 m (a length of 5 m with a sheath of 3 mm diameter would be desired) - Linear polarization at better than 20:1 - Scanning without mode jumps (Hope Free Mode) over a range greater than 7 GHz - Input of external modulation for feedback on the laser frequency with a bandwidth greater than 1 MHz Electronics for current control and temperature stabilization of the laser system Electronics for controlling the frequency of the laser system 1 : - a PI/PID type servo module with a bandwidth of at least 30 kHz; - a modulation/demodulation module (Pound-Drever-Hall type) operating at 20 MHz making it possible to generate an error signal from the spectroscopy signal of the rubidium. The 20 MHz reference oscillator is included in this call for competition (AC). The modulation is carried out by means of an electro-optical modulator (EOM) which is not part of this AC. System 2 (cooler): Laser emitting at 780.24 nm on the D2 line of Rubidium with the following characteristics: Useful fiber output power greater than 1W at the nominal wavelength - Line width (linewidth) of the free laser less than 500 kHz at 1 ms - Fiber output, FC/APC connector, with single-mode fiber with polarization maintenance of length greater than 1.5m (a length of 5m with a 3mm diameter sheath would be desired) - Linear polarization better than 100:1 - ASE -35db at...
