text: "This thesis describes the development of an atom interferometer designed
to exploit the\r\nadvantages of utilizing quantum entanglement for enhanced precision
measurements beyond\r\nthe standard quantum limit. While the project remains ongoing,
significant progress has been\r\nmade.\r\nA key contribution of this work is the
development of Quantrol, an experimental control\r\nsystem leveraging the ARTIQ
framework. This software enables precise timing and control\r\nwithout requiring
prior knowledge of ARTIQ’s implementation details or coding experience.\r\nThe
interface offers user friendly visual comprehension of the experimental sequence
and\r\nextended capabilities, allowing researchers to scan variables with a simple
click of a mouse.\r\nThe main proposed project is to implement atom interferometric
sequence with squeezed input\r\nstates inside of a dipole trap generated by a
high finesse cavity. The presence of the dipole\r\ntrap allows one dimensional
atomic cloud split while maintaining relatively strong confinement\r\nin other
directions.\r\nWe are currently able to trap and cool 87Rb atoms to few micro
kelvin temperatures, load\r\nthem into the dipole trap and state prepare them
to be used for squeezing and interferometric\r\nsequence."

text: We unveil a powerful method for the stabilization of laser injection locking
based on sensing variations in the output beam ellipticity of an optically seeded
laser. The effect arises due to an interference between the seeding beam and the
injected laser output. We demonstrate the method for a commercial semiconductor
laser without the need for any internal changes to the readily operational injection
locked laser system that was used. The method can also be used to increase the
mode-hop free tuning range of lasers, and has the potential to fill a void in
the low-noise laser industry.

text: Lasers with well-controlled relative frequencies are indispensable for many
applications in science and technology. We present a frequency-offset locking
method for lasers based on beat-frequency discrimination utilizing hybrid electronic
LC filters. The method is specifically designed for decoupling the tightness of
the lock from the broadness of its capture range. The presented demonstration
locks two free-running diode lasers at 780 nm with a 5.5-GHz offset. It displays
an offset frequency instability below 55 Hz for time scales in excess of 1000
s and a minimum of 12 Hz at 10-s averaging. The performance is complemented with
a 190-MHz lock-capture range, a tuning range of up to 1 GHz, and a frequency ramp
agility of 200kHz/μs.
