Blue Laser Pointer

This volume describes the theory and practical implementation of three techniques for the generation of blue-green light: nonlinear frequency conversion of infrared lasers, upconversion lasers, and wide bandgap semiconductor diode lasers. In addition, it looks at the various applications that have driven the development of compact sources of blue-green light, and reflects on the recent application of these lasers in high-density data storage, color displays, reprographics, and biomedical technology.

Shuji Nakamura's development of a blue semiconductor laser on the basis of GaN opens the way for a host of new applications of semiconductor lasers. The wavelengths can be tuned by controlling the composition. For the first time it is possible to produce lasers with various wavelengths, ranging from red through yellow and green to blue, in one substrate material. This fact, together with their high efficiency, makes GaN-based lasers very useful for a wide spectrum of applications. The second edition of this basic book on GaN-based devices has been updated and significantly extended. It includes a survey of worldwide research on GaN, as well as Nakamura's latest important developments. The reader finds a careful introduction to the physics and properties of GaN. The main part of the book deals with the production and characteristics of GaN LDs and LEDs. To complete the spectrum of applications, GaN power devices are also described.

Laser pointer - A laser pointer is a product that includes a small, inexpensive laser in a portable, pen-shaped format. Due to their low output, laser pointers do not project a visible beam in normal, clear air - rather, their light is visible as a small point of light where the beam intersects a surface.

Blue laser - Blue lasers have applications in many areas, from opto-electronic data storage at high-density, to medical applications. Until the mid 1990s blue lasers were large and expensive gas laser instruments which rely on population inversion in rare gas mixtures and need high currents and strong cooling.

Polish blue laser - The first Polish blue laser ( third in the world ) was constructed at Unipress by a 30-man team headed by Prof. Sylwester Porowski, on December 12 2001, The Polish scientists obtained crystals of gallium nitride under very high pressure using a completely unique technology, characterized by less defects and more effective than silicon carbide.
