Optoelectronic integrated circuits incorporating twin ring diode lasers with InAs/InGaAs/GaAs quantum-dot active region have been fabricated and characterized. Directional control and unidirectional operation of ring diode lasers are demonstrated by forward biasing an S-section waveguide incorporated within the ring cavity. Mode-beating spectra from individual ring diode lasers are observed at ...

High power, high brightness diode lasers are beginning to compete with solid state lasers, i.e. disk and fiber lasers. The core technologies for brightness scaling of diode lasers are optical stacking and dense spectral combining (DSC), as well as improvements of the diode material. Diode lasers have the lowest cost of ownership, highest efficiency and most compact design among all lasers. Mult...

Compared to traditional lasers, diode lasers are generally small, reliable and easy to operate. However, tuning characteristics of many commercially available standard diode lasers are often far from ideal. External Cavity Diode Lasers (ECDL), in which antirefl ection (AR) coated Fabry Perot laser diodes can be utilized, provide an attractive alternative with wavelength tuning ranges of up to 1...

This report presents an overview of the Diode Laser; its construction, function and application. Lasers in the form of laser diodes are in widespread use today. Diode lasers are used in a large number of industrial applications; the most prevalent use of the laser diode is probably in CD and DVD drives for computers and audio/video media systems. Diode lasers are also used in many other applica...

Diode lasers have a broad wavelength range, from the visible to beyond 2.2μm. This allows for various applications in the defense sector, ranging from classic pumping of DPSSL in range finders or target designators, up to pumping directed energy weapons in the 50+ kW range. Also direct diode applications for illumination above 1.55μm, or direct IR countermeasures are of interest. Here an overvi...

The dynamics of two mutually coupled chaotic diode lasers are investigated experimentally and numerically. By adding self-feedback to each laser, stable isochronal synchronization is established. This stability, which can be achieved for symmetric operation, is essential for constructing an optical public-channel cryptographic system. The experimental results on diode lasers are well described ...

III The use ofdiode lasers instead ofHashlamps as optical pump sources for solid state lasers offers significant advantages such as higher efficiency and longer lifetime. We have demonstrated three novel lasers based on this technology. The first is a zig-zag slab laser pumped by hybrid planar microchannel-cooled diode arrays that allow high-repetition-rate operation in a pulsed mode. The secon...
