   ILX LIGHTWAVE LCM-39427 (39427)   Description / Specification:    
ILX LIGHTWAVE LCM-39427 500 mA Laser Diode Driver, 12 W TEC Combination Module

The ILX Lightwave LCM-39427 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, constant power operation modes, and analog modulation. The LCM-39427 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. Specifications. Output Current Range: 0 to 500 mA. Laser Output Compliance Voltage: 0 to 6.0 V. Current Output Short-Term Stability (1 h): 25 ppm. Current Output Long-Term Stability (24 h): 50 ppm FS. TE Current: -2.00 to +2.00 A. TEC Short-Term Stability (1 h): <±0.05 °C. TEC Output Long-Term Stability (24 h): <±0.1 °C. TEC Ripple/Noise (rms): <1 mA. Temperature Range: –99.9 to 99.9°C. Output Power: 12. Photodiode Reverse Bias: 0 to 5 V. Photodiode Current Resolution: 1 µA.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence is the pattern and or relationships of waves due to phase properties.

Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
