Safety precaution for handling optical semiconductor devices
General:
Although manufacturer is always striving to improve the reliability of its products, problems and errors may occur with
semiconductor devices. Hence, it is necessary that user’s own products are designed with full regard to safety by
incorporating redundancy, fire prevention, and error prevention, so any problems or errors with semiconductor device
do not cause accidents, which might result in injury, death, fire, or environmental hazard. The following requirements
must be strictly observed.
Warning!
1. Safety standard of laser devices
Please follow closely to international standard (e.g. IEC 60825-1) or standard of each country (ex. JIS C 6802 in
Japan).
2. Laser characteristics and its danger
When laser device is operated at over-driven condition, low temperature, pulsing mode, and so on, it could emit
higher optical power than absolute maximum rating, and peak optical power might increase in conjunction with
relaxation oscillation. Laser device could lase at different wavelength with different case temperature, or different
output power. Laser devices are deviated on threshold current, operating current, operating voltage, slope efficiency,
peak wavelength, beam divergence, and so on. Not only light output power, but also polarization or far field patterns
might change as operating time goes by. If customers need more information of laser device, please contact Mitsubishi
Electric.
Laser light from each device might seriously injure human eyes and skin. Customer should design and manufacture
carefully their application products based on not only laser light characteristics but also LD characteristics, in order to
avoid human injury. Mitsubishi Electric is not responsible for any accidents that are caused by customer’s products.
If customers plan to release medical or aesthetic products with laser device, they should obtain their government’s
laser safety authorization.
3. Avoid laser light from entering human eyes
In normal operation, semiconductor laser device emits laser light. Laser light entering eyes could cause extreme
damage. Never look against laser beam direction, and never look directly through an optical system such as a lens.
Use an ITV camera to observe laser light. Mitsubishi Electric recommends that customers should explicitly label their
laser products with warning sign of eye injury.
4. Handling of device
Gallium arsenide (GaAs) is used in laser device. To avoid danger, strictly observe the following cautions:
Never place the device in human mouth. Never burn or break the device. Never use any type of chemical treatment to
reduce it to gas or powder. When disposing device, always follow any applicable laws, as well as customer’s internal
waste treatment regulations.
5. Disposal of device
Laser device uses Gallium arsenide (GaAs). It should be disposed as a specially controlled industrial waste, and it
should be separated from general industrial and household wastes, according to any “Law of Wastes and Cleaning”.
Caution!
1. High temperature
During operation device may become hot, therefore do not directly touch it during operation. The device could remain
hot even after power is turned off, so wait until it cools down prior to touching to avoid any burn. Never place any
inflammable substance that may cause fire near the device.
Specifications are subject to change without notice.
