PVG Series of Single-epitaxial-layer 1550 nm Pulsed Semiconductor Lasers
High Power Laser-Diode Family for Eye-Safe Range Finding
Excelitas Technologies’ PVG series of high power pulsed laser diodes are multi-quantum well devices with active
layers fabricated using advanced MOCVD epitaxial growth techniques. The devices are offered housed in two
convenient hermetic package configurations, either the “S” package, a TO-18 style low inductance package, or the
“R” style, a CD 9 mm outline, providing increased thermal dissipation with the option of accommodating a rear facet
monitor photodiode.
This series of devices are wavelength-centered at 1550nm primarily to take advantage of a significant increase over
AlGaAs and InGaAs lasers in the maximum permitted emission level with respect to Laser Institute of America or
International Electrotechnical Commission (IEC) requirements. It should be possible therefore to incorporate these
diodes into a system and operate them at relatively high average powers within Class I conditions. It is however the
responsibility of the user to certify their equipment as Class I and ensure that it meets the requirements of its
appropriate local regulatory agency.
The output wavelength of this series is well matched to the near peak spectral response of Excelitas InGaAs
photodiodes types C30617H, C30618H, C30619H, C30645H and C30662H, amongst others.
