Abstract:

Laser Diodes (LDs) are semiconductor coherent lightening devices which are widely used in many fields such as defence, industry, medical and optical communications. They have advantageous characteristics such as having higher electrical-to-optical and optical-to-optical conversion efficiencies from pump source to useful output power when compared to flash lamps, which makes them the best devices to be used in range finding applications. Optical output power of lasers depends on current through LDs. Therefore, there is a relationship between operating life and work performance of LDs and perfor

Approved for public release; distribution unlimited.<br>This thesis presents the design, implementation and evaluation of a depowered, stabilized-output laser diode drive unit for use in an analog fiber- optic communication transmitter. The driver circuits provide for a stable temperature-controlled operating environment by monitoring the thermistor in the laser diode module and by controlling the current to the module's integral thermoelectric cooler. Output optical power is maintained at desired bias and peak-to-peak levels by processing the signal from the monitor photodiode and amplifying

Abstract:

Since most of the energy input is converted to thermal energy in laser applications, the proper thermal management of laser systems is an important issue. Maintaining the laser diode and crystal temperature distributions in a narrow range during the operation is the most crucial requirement for the cooling of a laser system. In the present study, thermoelectric cooling (TEC) of a 1064 nm wavelength diode pumped laser source is investigated both experimentally and numerically. During the heat removal process, the thermal resistance through and between the materials, the proper integration of th

Abstract Although gain-switching is a simple, well-established technique for obtaining ultrashort optical pulses generated with laser diodes, the optical energy in a pulse achievable from commercial structures using this technique is no more than moderate and the ‘spiking’ behaviour seen at turn-on is likely to evolve into trailing oscillations.

碩士<br>國立清華大學<br>工程與系統科學系<br>104<br>This thesis includes two parts, namely the laser diode driver circuit design and low-voltage differential signal circuit design and measurement, both of them will be described in detail in each part of the design flow and illustrated the principle of operation by intuition. Laser diode driver circuit design includes the use of circuit simulation software and layout of the whole laser diode driver circuit. Also how to simulate the fiber modules. The light signals pass through the optical fiber because of chromatic dispersion and other effects caused by the

碩士<br>逢甲大學<br>電子工程所<br>99<br>Here, proposed a high speed and large current laser diode driving circuit with low sensitivity to process variation and improvement on overshoot performance, mostly applied in the DVD player. In the large current and high speed output laser diode driver circuit, in order to improve signal integrity, and reduce the impacts caused by temperature, voltage, process and environmental. Therefore, modifications on the Combination Switch Mode Laser Diode Driver Architecture [9]was made. So we proposed the Source Degeneration Type Combination Switch Mode Laser Diode Driver

Abstract:

Cavity ring-down spectroscopy has been used over the last twenty years as a highly sensitive absorption spectroscopic technique to measure light attenuation in gases, liquids, and solid samples. An optical cavity is used as a multi-pass cell, and the decay time of the light intensity in the cavity is measured, thereby rendering the techniques insensitive to light intensity fluctuations. Optical waveguides are used to build the optical cavities presented in this work. The geometries of such waveguides permit the use of very small liquid sample volumes while retaining the advantages of cavity ri
