Fiber Output Laser Diode Bar Module L15856-01 ■ Features ● Radiant power: 240 W ● Fiber core diameter: 400 µm ● Capable of outputting laser diodes (LD) temperature and humidity in the package ● Equipped with a leakage sensor ● Built-in photodiode (PD) for radiant power monitor ■ Applications ● Exciting a solid state laser ● Selective laser heating ■ Outline This is a fiber output LD bar module using 940 nm LD bars. It can output the information of temperature of its built-in LD, humidity in the package, leakage and radiant power through D-sub connector. Also, it uses a water cooling method that does not require pure water. ■ Absolute maximum rating Top(c) = 25 °C except for temperature parameter Parameter Symbol Φef Fiber end radiant power *1 If Forward current Vr Reverse voltage Top(ld) Built-in LD temperature *2 Top(a) Operating ambient temperature *3 Tstg Storage temperature *3 — Humidity inside chassis *4 — Cooling water medium — Cooling water particles Coolant Cooling water temperature — condition (cooling water in side) — Cooling water pressure *6 — Cooling water flow rate (overall) *6 *1 Output adjusted and measured by "● Test fiber specification". *2 Temperature that is measured between pins 7 and 20 or pins 8 and 21 of the main unit sensor terminal (see "■ Pin assignment"). *3 No condensation *4 Humidity when laser is not emitted, which is measured between pins 23 and 25 of the sensor terminal (see "■ Pin assignment"). *5 Water quality must be higher than that of distilled water. *6 Including surge pressure. * Indicating limits that must not be exceeded instantaneously and shall not exceed any one value.
