All standard mounts in the LDM-4980 series feature fully configurable laser and temperature control connections. This allows the flexibility to accommodate virtually any laser diode pin configuration. In addition, these mounts have the ILX Lightwave® standard 9-pin D-sub input connections to make setup and configuration consistent and easy.

The LDM-4983T version is equipped with an external case temperature control option. The external case temperature control allows for control of laser package temperature, resulting in simultaneous and independent temperature control of both laser die temperature and package temperature. It is ideal for applications requiring tight temperature stability, different case temperatures, or for testing laser diodes at a wider temperature range than can be accomplished with the internal TEC alone.

The LDM-4983 mount allows single-side Butterfly-package clamping and electrical connection using a single flat ZIF socket to facilitate ease of mounting and to minimize strain on device leads. Once installed in the socket and clamped, the entire laser package bottom surface is clamped to a heat sink.

The LDM-4983 is designed for “one-sided butterfly” packages that have the modulation input on one side and seven or thirteen pins on the other side. These packages are typically used for 10 Gb/s internally modulated laser modules. A special electrical terminal allows you to configure the potential of the hotplate and laser module case (grounded, floating, or at a specified potential).
