High-power Laser Diodes: Diode-laser enhancements boost efficiency and reliability

Sept. 1, 2019
Passively cooled high-power laser diodes with nonsoldered joints and new cooling scheme show high reliability under hard-pulsed and continuous-wave operation.
FIGURE 1. A schematic shows the operation of a basic flow cytometer. Cells are introduced into a laser beam in a liquid stream by hydrodynamic focusing, either with a nozzle or enclosed quartz flow cell. Signal collection optics collect excited fluorescence signals, which are steered to PMTs using dichroic mirrors and narrow bandpass filters. Modern instruments can utilize fiber optics for both laser delivery and signal collection.
