| Summary, etc. | Laser frequency stabilization is crucial for length metrology, since it is a perquisite for displacement interferometers. Frequency-doubled light at 532 nm from the microchip Nd:YVO4 lasers is a promising candidate to replace the widely used He-Ne lasers in length metrology due to their superior characteristics, low-cost and rugged structure.In this thesis, a single frequency stabilizedDiode-Pumped Solid-State (DPSS) Nd:YVO4 laser is constructed for length metrology. The thesis includes five chapters: the first chapter explains the importance of laser frequency stabilized in different length metrology applications. Chapter 2 describes the comparison between different types of lasers. Chapter 3, briefly describes different laser parameters measurement techniques. Chapter 4 describes briefly some different laser frequency stabilization techniques for the (DPSS) laser.Chapter 5 includes the experimental work and results.<br/>The following experiments were performed:<br/>• Investigation of the longitudinal modes and the mode spacing of different types of He-Ne lasers.<br/>• Testingdifferentmicrochip Nd:YVO4 laser modules.<br/>• Construction of a single frequency stabilized DPSS Nd:YVO4 green laser for length metrology.<br/>• Spectral characteristics of a commercial microchip Nd:YVO4 are investigated. The laser temperature is initially controlled to facilitate the study of longitudinal mode structure of the laser at different pumping currents and temperatures. Additionally, a simple method is suggested to obtain a single-mode operation at a relatively wide temperature range, namely from 20 ℃ to 25.8 ℃, and pumping currents from 300 mA to 385 mA. <br/>• The frequency stability is evaluated after controlling the laser temperature to be 1.9 × 10-8 at 1 second. Additionally, parameters that are important for locking the frequency of the laser to a molecular reference transition are investigated such as, laser linewidth and the relation between current/temperature and wavelength.<br/> |
