Triggering GaAs lock-on switches with laser diode arrays

Integrated Power Conditioning for Laser Diode Arrays

For several years, the Laser Program at LLNL has been designing and building a variety of specialized compact laser systems 1. They offer extremely high energy densities for their size and are primarily used in medical and military applications where a high premium is placed on both reliability and compactness. These systems are based upon a 2 cm-x-2 em liquid cooled wafer (Fig. 1) that support...

Analytical Beam Shaping with Application to Laser Diode Arrays

In contrast to numerical methods for beam shaping, analytical beam shaping consists of two steps: rst, nding a purely geometrical distortion between the input and output plane redistributing the intensity of the incoming wavefront and second, computing a phase-only element realizing this coordinate transform. For the latter the method of stationary phase may be applied. The known classes of pos...

Photoconductive Semiconductor Switches: Laser Q-switch Trigger and Switch-Trigger Laser Integration

This report provides a summary of the Pulser In a Chip 9000-Discretionary LDRD. The program began in January of 1997 and concluded in September of 1997. The over-arching goal of this LDRD is to study whether laser diode triggered photoconductive semiconductor switches (PCSS) can be used to activate electro-optic devices such as Q-switches and Pockels cells and to study possible laser diode/ swi...

The Development of Laser Diode Arrays for Printing Applications

Use of laser-diode arrays in holographic interconnections.

Holographic interconnection schemes for high-speed data transfer have been demonstrated by other researchers. Because holographic recording materials presently available are sensitive to the visible spectrum but not to the near infrared, these studies used bulky gas lasers. Visible laser diodes, as they become available, will likely become a preferred source in a practical system because of the...
