Bend Radius Short / Long Term >15/>30 mm Application Note: (1) For pulsed operation max peak power can be 1.2xPop if pulse time is <Sysec and average power is lower than Pop (c.w.) (2) Keep the heat sink at <= 35°. The heat sink should have a flatness of better than 0.02mm and a roughness grade not less than N7 (Le. Ra=1.6um) (3) Aconductive material between TO-220 laser diode module and the module base is highly recommended. The thermally conductive material should have a sufficient thickness and elasticity to compensate for the non-planarity between the module base and the heat sink surface (4) Electrostatic discharge (ESD) can lead to latent or catastrophic failure of a multimode laser diode module (5) The power supply should have a transient suppression and an over-voltage protection. Before connecting the module to the power supply and during Power off the power supply output should be short circuited (6) By no means should the fiber be touched by hot solder because this can lead to lower output performance and reliability. During the soldering process the fiber temperature should always be below 85°C (7) The limits for the bending radius prevents mechanical cracks. The bending radius limit for the optical power loss is higher. Please take into account a possible output power reduction of up to 2% below a bending radius of 500(1000) x core diameter for NA 0.22(0.15). (8) The intensity profile at the fiber end facet and the far field ex fiber may vary between a gaussian shape and a donut shape.

Tin, soldering 250 Cc LD Forward Current cw, lop, max 6 A LD Reverse Voltage Va, max 2 v Rel. Humidity 0 5 % Note: (1) Absolute maximum ratings may be applied to the laser module for short period of time only. Exposure to ‘maximum ratings for extended period of time or exposure above one or more max ratings may cause damage or affect the reliability of the device (2) Improper pin bending can crack the glass sealing between pin and the package and hermeticity of the package may be lost and may damage the laser diode by humidity level below the dew point inside the package. If pin bending is necessary pins must be fixed mechanically over a short length in the original flat position such that the bending force is absorbed by a mechanical fixing tool (claw etc).
