Laser Diodes with Fiber Connection (CW and Pulsed)

DFB Triplexer Modules

The 1 mW triplexer laser module was designed for use in fiber-optical testing devices for which several wavelengths are required. The wavelengths 1310 nm, 1490 nm, and 1550 nm, which can be used simultaneously, are integrated into a small housing and coupled into an SM fiber.

405 nm cw Laserdioden

The K41 and CS405 series emit an optical power of 20 mW to 100 mW from the fiber at a wavelength of 405 nm.

Pulsed Laser Modules

Pulsed laser modules of the PL13 and PL15 series from PD-LD, Inc. are mainly used for optical measurement devices like OTDR (Optical Time Domain Reflection). They comprise InGaAsP diodes at 1310 nm or 1550 nm and a spectral width typically of 7 nm. Depending on the wavelength output power can range from 60 to 120 mW, threshold current from 20 to 30 mA, and the operating current from 30 to 50 mA. The operating voltage is 3 V. Rise and fall times are 1 ns. The pulse width is specified with 10 ns at a duty cycle of 1%. The laser diodes are offered in different housings, which have been made using a new YAG laser welding system. These housings are extremely stable mechanically. Versions are available for PCB or front plate mounting and either with common optical connectors (FC, ST^®, SC) or with fiber coupling (9/125, 50/125, 62,5/125, 100/140 µm, and many more).
