Voltage of our blue-violet laser diode is 4-6V, which is higher than 1.8-3V of the other laser diodes. Take care of operating voltage when you design an APC circuit. 2. An assemby line has to be protected from static electricity or surge current. Use an earth-band or the like when handling blue-violet laser diodes. 3. Output light from our blu-violet laser diode is very reactive and harmful to a human eye. Avoid looking at the output light directly or even indirectly through a lens while oscilating. Parts exposed to the output light such as a lens or body should be made from material strong for ultraviolet damage. 4. Don't use our blue-viole laser diode with a built-in monitor photodiode for an application which requires power controll with high accuracy. 5. Reselling, disassembling, or reverse engineering of a blue-violet laser diode is prohibited. 6. Our laser diode is not intended for use in applications where extremely high reliability is required, or human life is directly involved, e.g. life-support systems or cars. 7. We are not liable to any undesirable result caused by a misuse or inappropriate use. Export Control 1. Our laser diode is subject to the export control regulations (of foreign exchanges and foreign trading). When exporting laser diodes (including service), care should be taken to insure that any necessary procedures are complied with. 2. Laser diodes should be destroyed in cases when they are not be used to avoid infringing on export. 3. Use in military applications is prohibited.
