MEASUREMENT EXAMPLES

The C4258 series of picosecond photodetectors consists of pho-

todetectors featuring a light detector, a high-frequency circuit,and

a battery integrated in a single unit, as well as fast response. Opti-

cal phenomena in the picosecond region can be measured sim-

plyby irradiating the unit with an optical beam and connecting the

output to an external oscilloscope.

A high-speed MSM photodiode is used as the detector, enabling

a fast rise time , a large active area. For this reason, the C4258 is

ideal for pulse waveform observation of picosecond lasers such

as Ti: sapphire / YAG lasers, and semiconductor lasers for

DVDs and optical communications. In addition, by combining it

with a short-pulselight source, the C4258 can be used in applica-

tions such as measuring the transmission characteristics of opt-

ical fibers.

Four models are available. This lets the user select which ever

model is optimum for the wavelength of the pulse being meas-

ured.

semiconductor laser in the 0.8 µm band
