405nm, 350mW Violet Laser Diode, Manufactured by SHARP, GH04W102GC

Product Overview:

These 405nm diode lasers from SHARP electronics, manufactured part number GH04W10A2GC, come in a two pin TO-can package. These lasers are class 4 of IEC60825-1 devices. The can type is a 5.6 floating package with a photodiode and zener diode. This product is offered in a hermetically sealed package in which the blue violet laser diode chip is mounted. The laser chip can be easily damaged by air or moisture. The following precautions should be taken when handling these devices: The glass on the package window is quite thin and is susceptible to cracking when handling. Therefore, caution should be taken to avoid any mechanical shock or to over-tighten the header when soldering or attaching to a PCB. The anode and cathode pins can be over-stressed and are easily bent.

Safety:
The beam emitted by this laser diode is potentially harmful to the human eye. The following precautions should be taken: When this product is being operated, the laser beam should not be viewed either directly or through a lens, microscope or optical fibers. When operating this product, proper laser safety glasses should be worn at all times. Appropriate measures, such as fail-safe design and redundant design should be taken to ensure reliability and safety when this product is used for equipment which demands high reliability and safety in function and precision.

Proper Handling and Operation of Laser Diodes:
Laser diodes are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
