This book was released on 2017-03-02 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The German Space Agency DLR is supporting a sounding rocket mission that aims to generate a Bose-Einstein-Condensate (BEC) onboard a sounding rocket in 2017. At the time when the research and technical developments described in this thesis were initiated, there were no laser technologies available meeting the requirements regarding compactness and reliability. This work is therefore devoted to developing the required laser technologies that will provide a demonstration of BEC and atomic interferometry in space for the first time ever. This research was carried out as part of the project ”LASUS” which provided the technology development for the sounding rocket mission ”MAIUS”. In the framework of this thesis, concepts were developed to realize micro-integrated extended cavity diode lasers (ECDLs) for rubidium (Rb) and potassium (K) spectroscopy. The ECDL modules contain only non-moveable components that are integrated on a micro-optical bench with footprints of 50 x 10 mm2 and 80 x 25 mm2. They are based on a Littrow configuration with an external cavity length of ~30 mm. The micro-integrated ECDLs provide an output power ≥ 35 mW behind a micro-optical isolator with 30 dB isolation and a short-term (170 µs) FWHM linewidth of significantly less than 100 kHz. The intrinsic linewidth corresponds to only 260 Hz. To qualify the micro-integrated ECDLs for future quantum optics precision experiments in space, vibration tests (8.1 gRMS and 21.4 gRMS) and mechanical shock tests (1500 g) were carried out. No degradation of the electro-optical performance was observed. Moreover, the electro-optical properties of the macroscopic ECDLs were optimized for micro-integrated ECDL modules. Further, distributed feedback diode (DFB) lasers were electro-optically characterized and optimized, again for Rb and K spectroscopy. Rb-DFB lasers provide single mode emission with an output power of more than 180 mW. The K-DFB lasers feature an excellent spectral stability with a short term (10 µs) FWHM linewidth of 320 kHz, and their intrinsic linewidth corresponds to 5 kHz.

Download or read book Laser Diode Modulation and Noise written by Klaus Petermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser diodes represent a key element in the emerging field of opto electronics which includes, for example, optical communication, optical sensors or optical disc systems. For all these applications, information is either transmitted, stored or read out. The performance of these systems depends to a great deal on the performance of the laser diode with regard to its modulation and noise characteristics. Since the modulation and noise characteristics of laser diodes are of vital importance for optoelectronic systems, the need for a book arises that concentrates on this subject. This book thus closes the gap between books on the device physics of semiconductor lasers and books on system design. Complementary to the specific topics concerning modulation and noise, the first part of this book reviews the basic laser characteristics, so that even a reader without detailed knowledge of laser diodes may follow the text. In order to understand the book, the reader should have a basic knowledge of electronics, semiconductor physics and optical communica tions. The work is primarily written for the engineer or scientist working in the field of optoelectronics; however, since the book is self-contained and since it contains a lot of numerical examples, it may serve as a textbook for graduate students. In the field of laser diode modulation and noise a vast amount has been published during recent years. Even though the book contains more than 600 references, only a small part of the existing literature is included.

Download or read book A compact mode locked diode laser system for high precision frequency comparison experiments Band 64 written by Heike Christopher and published by Cuvillier Verlag. This book was released on 2021-04-09 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical frequency combs (OFC) have revolutionized various applications in applied and fundamental sciences that rely on the determination of absolute optical frequencies and frequency differences. The latter requires only stabilization of the spectral distance between the individual comb lines of the OFC, allowing to tailor and reduce system complexity of the OFC generator (OFCG). One such application is the quantum test of the universality of free fall within the QUANTUS experimental series. Within the test, the rate of free fall of two atomic species, Rb and K, in micro-gravity will be compared. The aim of this thesis was the development of a highly compact, robust, and space-suitable diode laser-based OFCG with a mode-locked optical spectrum in the wavelength range around 780 nm. A diode laser-based OFCG was developed, which exceeds the requirements with a spectral bandwidth > 16 nm at 20 dBc, a comb line optical power > 650 nW (at 20 dBc), a pulse repetition rate of 3.4 GHz, and an RF linewidth of the free-running pulse repetition rate < 10 kHz. To realize a proof-of-concept demonstrator module, the diode laser-based OFCG was hybrid-integrated into a space-suitable technology platform that has been developed for future QUANTUS experiments. Proof of sufficient RF stability of the OFCG was provided by stabilizing the pulse repetition rate to an external RF reference. This resulted in a stabilized pulse repetition rate with an RF linewidth smaller than 1.4 Hz (resolution limited), thus exceeding the requirement. The developed diode laser-based OFCG represents an important step towards an improved comparison of the rate of free fall of Rb and K quantum gases within the QUANTUS experiments in micro-gravity.

Download or read book Laser Diode Beam Basics Manipulations and Characterizations written by Haiyin Sun and published by Springer Science & Business Media. This book was released on 2012-06-16 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many optical design technical books are available for many years which mainly deal with image optics design based on geometric optics and using sequential raytracing technique. Some books slightly touched laser beam manipulation optics design. On the other hand many books on laser diodes have been published that extensively deal with laser diode physics with little touching on laser diode beam manipulations and characterizations. There are some internet resources dealing with laser diode beams. However, these internet resources have not covered enough materials with enough details on laser diode beam manipulations and characterizations. A technical book concentrated on laser diode beam manipulations and characterizations can fit in to the open and provide useful information to laser diode users. Laser Diode Beam Basics, Manipulations and Characterizations is concentrated on the very practical side of the subject, it only discusses the basic physics and mathematics that are necessary for the readers in order to understand the subject. This book is intended to provide a practical guidance and reference to those scientists and engineers who are still new to laser diode applications, and to those undergraduate and graduate students who are studying lasers and optics. Readers are expected to be able to fast and easily find the most practical and useful information about laser diodes in this book without the need of searching through a sea of information.
