Improved, Simple Laser Diode Control
May 2010Wavelength Electronics Inc.Request Info
Two PCB mount components simplify complete laser diode control. The WLD3343 laser diode driver supplies up to 2.2 A precision current for laser diodes. The WTC3243 temperature controller drives up to 2.2 A and can stabilize to 0.0009 °C. Laser diode and thermoelectric safety circuits are integrated. Variations of the WLD3343 up to 3 A are available. Improvements include lower noise and better stability for scans across ambient.
