The TO9F from SemiNex Corporation is a single-mode fiber-coupled TO-9 laser diode that operates between 1300 and 1700 nm. The 1550 nm TO9F delivers an output power of 175 mW CW at 1 A drive current. For pulsed applications (<150 ns pulse width and <0.1% duty cycle) the 1550 nm device will deliver about 550 mW of optical power. The 1310 nm TO9F delivers 200 mW CW and 650 mW pulsed. The laser diode measuring only 17 mm wide, 10.5 mm tall and 26 mm long encased in a 17 mm x 10.5 mm x 5 mm cooling block with screw holes for effective thermal mounting.
