The EM4 P219 line of single mode, cooled 980 nm pump lasers deliver up to 420mW of fiber-coupled power. The modules are
packaged using the unique, patent pending technology Uniline™ for permanent fiber alignment. Uniline™ provides superior
end-of-life optical and electrical performance, achieved by maintaining a highly stable, all-axis alignment lock between the laser
chip and the tip of the single-mode fiber.
The hermetically sealed 14 pin butterfly package is available with a fiber Bragg grating and includes thermoelectric cooler, ther-
mistor, monitor photodiode and UniDry™ getter. The fiber Bragg grating precisely locks the center wavelength over extended
power and temperature range. Center wavelengths in the range of 976 nm to 980 nm are available with tight wavelength control.
EM4’s Uniline™ family of pump lasers are qualified to meet the requirements outlined in Telcordia GR-468-CORE.
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and operation of the
device at these or conditions beyond these are not implied. Exposure to absolute maximum ratings for extended periods of time may affect device reliability.
