Abstract

This paper presents the design of a high-frequency pulsed inductive wireless power transfer system for quantum-cascade lasers (QCLs). QCL is a highly flexible type of laser and operates from low- to mid-infrared wavelength. The high optical power output, tuning range, and room temperature operation make QCLs useful for spectroscopic applications such as remote sensing of environmental gases and pollutants in the atmosphere. Wireless power transfer (WPT) enables QCLs to operate in conditions where traditional wired QCL cannot. We present the design of a high-frequency pulsed Class-E transmitter and a full- bridge diode receiver WPT system to drive a QCL. The converter operates at 6.78 MHz to create a pulsed 2 μs 10 V/1.2 A output with a peak efficiency of 60.0% at a nominal distance of 0.1 cm.
