Dr. Bidoor AlSaif
Researcher, CIPR
Great interest in laser light, particularly, CW lasers stabilization using optical frequency comb for spectroscopic metrology and gas sensing applications. Developments of gas sensors in mid infrared (MIR) region with high sensitivity and precision has been achieved during the phd program. Moreover, I do have experience and interest in microfabrication of semiconductor devices that are usually fabricated in high class cleanrooms and perform both chemical and physical deposition/etching tools. Not to mention to stat of art characterizations tools of thin-films such as SEM, X-ray and AFM that is a must for the quality of fabrication process.
