This laser diode emit high intensity visible light which can be hazardous to the human eye. Color output: 445nm - Blue. Continuous optical output power: 2.0W - 2.1W. 4.5 - 5.0V.
Small package TO-18: 5.6mm. Test: Current = 1.8A -> Output power 2.2W Efficiency 28%. Negative current transients greater than 25 µA or reverse voltages >4V, can destroy the LD. This LD is needed very good cooling on in large current >1.4A.
Temperature on socket over 70 degree celsius is detrimental for the diode. Without a cooling system: overheat and destroy to 3S after power on.
Rear side used for cooling, recommended 5mm thickness copper plate with triangle hole for pins. This laser diode needs Driver - NOT included. For focusing requires 445nm three Layer coated glass focusing lens - NOT included.Attention: The following practices should be followed to minimize damage to static sensitive devices. After removed from anti static packing. Handle laser diode by the body. Do not slide laser diode over any surface. Only grounded tip soldering irons should be used.
Connect to ground Soldering Wire with Rosin Core. Shorted both pins after finished. Remove Short after connect to driver. Use quality Constant Current Driver for this LD - accurate Current and Voltage. Direct connect to Standard Power Supply will damage the LD.Do not use multimeter for testing of this LD - not show anything, you will probably damage LD. Digital multimeter use to 4V for measurement of Diode, if you connect forward to LD will not show anything Vf min = 4.2V. If connect reverse to LD you will probably damage LD Vr max = 4V.
Note: If you do not follow these, this will damage the laser diode. The item "2W / 2000mW 445nm Blue Laser Diode TO-18 5.6mm M140" is in sale since Friday, April 03, 2015.
