High-Power Laser-Diode DIP Module
OL5201N-25, OL5204N-25
GENERAL DESCRIPTION
The OL5201N-25 and OL5204N-25 are 1.55
mm,
extremely high-power laser-diode DIP modules
with single-mode fiber pigtails. The Multi-Quantum-Well (MQW) structure laser diodes
achieve a single-mode fiber output of over 25 mW. The modules are optimal light sources for
optical measuring instruments and other systems that require high-power.
