Embodiment Construction

[0015] An embodiment of the architecture of a current driver circuit for a diode laser system is shown and described whereby the circuit is modular and minimally complex with respect to the number of components and connections. By scaling, circuits may be less prone to failure and significant savings can be realized in system development and maintenance. While not limited thereto, an understanding of various aspects of the present disclosure can be gained from the following discussion in conjunction with the accompanying figures.

[0016] For example, figure 1 A block diagram of an embodiment of a diode laser system 100, equivalently a laser diode system 100, according to the present disclosure is shown. In general, diode laser system 100 is a kilowatt-class laser system for material processing and industrial applications (eg, for optical pumping of solid-state lasers). However, those skilled in the art will appreciate that the diode laser system 100 described below may be u...

Abstract

Consider the architecture of a current driver circuit for a diode laser system whereby the circuit is modular and minimally complex with respect to the number of components and connections.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application Serial No. 62 / 083,787, filed November 24, 2014, and entitled "EFFICIENT HIGH SPEED HIGH POWERCURRENT DRIVER FOR DIODES," which The entire contents are hereby incorporated by reference for all intents and purposes. Background technique [0003] Suppliers of laser solution products for commercial and scientific applications often face a number of hurdles when trying to bring a particular product to market. For example, the investment required to develop new implementation-specific circuits can be prohibitively expensive in many cases. To address these and other issues, an implementation of the architecture of a current driver circuit for a diode laser system is considered whereby the circuit is modular and minimally complex with respect to the number of components and connections. By scaling, circuits may be less prone to failure and significant savings can be r...
