Nichia M140 A-Type / A-140 Laser Diode - 1.8W - 445nm

This listing is for one M140 A-Type or A140 laser diode. The diode emits a 445nm wavelength with output power reaching 1.8 watts. Each diode is carefully extracted from a low hours laser diode array. Each diode is fully tested to ensure functionality.
 
You must know what you are doing before hooking these up. Reverse polarity, excessive current and high heat will damage or ruin these. A constant current laser diode driver is required to drive the diode, never connect directly to a battery. Recommended driving current is between 1A and 1.5A. The current should never exceed 1.8 amps!!! The diodes must be inserted into a laser diode module w/ heat-sink before energizing to dissipate heat. A glass lens should be used as well.
