Analog and Digital Modulation of LQx and DLx Series Laser Diode Modules
|
From Newport Corporation
The LQx series Fabry-Perot laser diode modules offers the most precise temperature control available from Newport Corporation. The DLx Series Distributed Feedback (DFB) Laser Source modules offer exceptionally stable wavelength and narrow spectral width. The LQC and the DLC series represent laser modules with a CW output. The LQA and DLA series represents laser modules with 20MHz analog beam modulation. The LQD and DLD series represents a laser module with 100MHz TTL digital modulation. Analog modulation requires an input voltage with 0 to 1 VDC modulation on the SMC Connector. A control voltage of 1V will yield a 100% power output. A control voltage of 0VDC will yield a 0% output. The digital, or the transistor-transistor logic (TTL), modulation requires an input voltage of 0 to 5 V. A control voltage of 5V will yield a 0% power output. A control voltage of 0V will yield a 100% output. The laser is either ON or OFF depending on the control voltage. Products & Services
Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output. They are also known as laser diodes.

Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation.
