E2V0020-37-X1 ¡ electronic components OL5201N-25, OL5204N-25 LASER DIODES OL5201N-25, OL5204N-25 1.55 mm High-Power Laser-Diode DIP Module 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.
