   ILX LIGHTWAVE LCM-39425 (39425)   Description / Specification:    
ILX LIGHTWAVE LCM-39425 500 mA Laser Diode Driver, 12 W TEC Combination Module

The ILX Lightwave LCM-39425 Current Source/TE Controller Module is a precision laser controller (current source and temperature controller) module for use in the LDC- 3900 Modular Laser Diode Controller. The integrated laser diode current source provides up to 500mA of high stability low noise current output with integrated laser diode protection circuits. Standard current source features include constant current and constant power operation modes. The LCM-39425 also includes a 12W thermoelectric temperature controller that is compatible with thermistor, IC and RTD temperature sensors providing convenience and flexibility over a broad range of temperature control applications.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
