Supply and Installation of 4W Ti:Sapphire Laser System to the University of Birmingham

The quantum technology transfer centre at the University of Birmingham is part of the Quantum Hub for Sensors and Metrology. We are looking for a Titanium sapphire laser for our strontium optical clock development and for use as a reference laser as part of our engagement with industry. • Target operation wavelength of 813nm. All specification will be referenced at the wavelength unless otherwise specified. • Pump laser should operate single frequency at 532nm. • Laser will operate in continuous wave (cw) mode. • Output power greater than or equal to 4 watts. • Linewidth less than 500kHz free running (100ms timescale) • Output wavelength should be continuously tuneable over the range of 725nm to 875nm or better. • Laser should remain locked for >1000 hours without dropouts. • Amplitude noise of 0.1% or better between 10Hz and 10MHz. • Long term RMS power stability of 0.1% or better. • Amplified spontaneous emission (ASE) of -75dB or better in the region +/- 50nm away from the carrier. • TEM00 output with an M2 of 1.1 or better (closer to 1) • Frequency scan of at least 10GHz/s • Frequency scan range of at least 10GHz without mode hop • Actuation for locking laser to external reference, e.g. High finesse cavity. • Output polarisation either horizontal or vertical with an extinction ratio of 100:1 or better. • Physical dimensions of laser head should be 30cm x 30 cm x 15cm (l x w x h) or less • The laser should have full computer software support. • Computer control should have easy integration with lab view and python based programming languages.
