6505 In Stock

The 6505 by Newport is a Laser Diode Driver Module that represents an integral component of the 6000 series Laser Diode Controller, expertly designed to seamlessly integrate and enhance laser diode functionality. The module's meticulous layout and advanced circuitry converge to yield an exceptionally stable output current source, complemented by its notable capacity for low noise emission owing to its low bandwidth attributes. Engineered primarily for communication applications, the 6505 boasts an internal function generator, a vital tool for comprehensive system testing. Users are empowered to modulate the laser diode output, a process contingent upon the precise programming of parameters such as lmin, lmax, and frequency within the module.

Facilitating precise control over laser output for a diverse array of applications, an external analog modulation input is judiciously incorporated into the 6505. Remarkably, this modulation capability extends to both constant power and constant current operational modes. A distinctive feature of this module is its integrated monitor photodiode, which can be configured in a zero-biased mode to accommodate continuous wave (CW) low noise scenarios, or up to 5 V in a reversed bias configuration to facilitate high-frequency modulation demands. Notably, the 6505 extends access to crucial parameters like the laser diode's forward voltage, achieved through a resolution of 16 bits.

The 6505 has array of time-tested protective measures including input power module filters, power regulation stages and supplementary filtering, and transient detection circuits with high speed. Collectively, these safeguards ensure uninterrupted laser diode operation by effectively mitigating transient interference. Further fortifications entail multiple output shorting circuits, a gradual turn-on sequence, and an autonomous current limiting feature. Emphasizing user convenience, the 6505 offers a service-free modular design, streamlining maintenance requirements. Calibration is contained within a closed-case environment, and the module seamlessly interfaces with the 6000 series controller for save and recall functional available on the front panel.
