DESCRIPTION
Mitsubishi ML501P73 is a high-power, highly efficient
semiconductor laser diode which provides emission
wavelength of 638 nm and standard light output of 1.0W
(pulse) and 0.5W (CW).
This LD has broad-stripe structure which enables high
output power.
Note1: The maximum rating means the limitation over which the laser should not be operated even instant time.
This does not mean the guarantee of its lifetime. As for the reliability, please refer to the reliability report issued by
Quality Assurance Section, HF & Optical Semiconductor Division, Mitsubishi Electric Corporation.

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.
