Laser diodes in the red spectral range have been used to date in laser distance measurement devices that are based on the phase shift principle. These laser diodes are operated with a very high modulation bandwidth, which is why DPSS lasers in the green spectral range are not suitable.
The PLT5 510 from OSRAM Opto Semiconductors is an inexpensive 10 mW laser diode thatmakes this application possible. Its green laser light – with a wavelength of 515 nm – is more advantageous than red light because the human eye can see green light far better than red light.
There are more advantages to using the PLT5 510: it comes in a user-friendly TO-56 housing with an integrated monitor photodiode and allows stable operation up to 60°C.
This operating temperature is also suited for laser leveling instruments with which tasks can be performed both indoors and outdoors under direct sunlight.
Further application fields include: pilot lasers, laser projectors, laser shows, biomedical and medical technology, and measurement technology.
