OSI Laser Diode has introduced the SCW 1532-500R high-power, pulsed laser diode module that features power higher than 500mW and operates at 1,550nm. It is suited for use in optical spectrum analysers (OSAs) and optical time domain reflectometers (OTDRs). The 14-pin butterfly package with an industry-standard pin-out offers good pulse drift performance and high stability. The 1,550nm high power laser diode module is the first in a series of three devices. Two more modules with 1,310nm and 1,625nm wavelengths, respectively, are in development.
The laser diode is optically coupled to an SMF fibre pigtail and includes a thermoelectric cooler (TEC) and an electrically isolated temperature-sensing thermistor. Other features of the 1,550nm pulsed laser diode module include optical power at 500mW, a threshold current of 70mA, and a typical forward voltage of 2V to a maximum of 3V. Moreover, standard connectors are optional, making the device easy to integrate into an existing or a new optical test and measurement system where high peak pulsed optical power is required.
OSI Laser Diode’s device offers operating temperature ranges from 0°C to 65°C and storage temperature (non-operational) ranges from -40°C to 85°C.
