STANFORD RESEARCH SYSTEMS LDC502 2000 mA Laser Diode Controller

The SRS LDC502 Laser Diode Controller is an ideal instrument for controlling the current and temperature of your laser diodes. It has the performance and features you expect from instruments costing twice as much. The LDC502 has up to 2 A of output current with less than 3.5 µA of rms noise. The SRS LDC502 is a 36 W high-precision temperature controller with standard computer interfaces, including Ethernet. It has multiple laser diode protection features, including slow start turn-on, adjustable current limits, and adjustable compliance voltage. Specifications. Current Source Range: 0 to 2 A, 0 to 1 A.

Bit Error Ratio (BER)
Bit Error Ratio (BER) is the ratio of errors caused by the number of bits in a data stream that have been altered due to noise, interference, distoriton or bit synchronization errors.

Variation of insertion loss on the passband of an optical device.

Polarization Dependent Loss (PDL)
Polarization Dependent Loss is the difference between the maximum and minimum values of loss due to the variation of the polarization states of light propagating through a device. PDL is expressed in decibels. Calculated by; PDL = 10 log10 (Ep/Es), where EP and ES are the measured diffraction efficiencies for P- and S-plane polarized incident light, respectively.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)

Wavelength Resolution
Wavelength Resolution is the smallest possible displayed wavelength increment/decrement.
