Product Description
Newport's new LQN Series Laser Diode (LD) Sources are designed for use with standard Newport Laser Diode Instrumentation, giving the user the ability to precisely control the laser diode current and temperature. LD Sources can be connected to the Newport Model 8000 Modular Controller, Model 6000 Laser Diode Driver, or 500B Series LD Driver and Model 300B TEC Controller via a standard Y-Cable. Once connected, they can be operated in CW mode by selecting a laser drive current or modulated by using the modulation feature found in most Newport Laser Diode Drivers. The laser temperature can be fixed for precise wavelength stabilization, or varied for wavelength tuning of the laser diode.
Warning: the temperature controller must be in operation in order to avoid possible diode damage. Otherwise, warranty is voided.
