Performance

Characteristics

• Internal digital modulation mode:

Free selection 200 Hz to 100 kHz.

All output signals are pulse shaped

duty cycle 50%.

• Internal coherence control for

linewidth broadening.

• ON-switching with fast output

power stabilization < 20 s.

• Output power “attenuation” at

default wavelength 6 dB in steps of

0.1 dB.

Tuning speed over full range 30 s.

• Polarization maintaining fiber orien-

tation: TE mode in slow axis, in line

with connector key.

Laser safety information

The 81663A DFB Laser Sources listed

above are classified as Class 1M

according to IEC 60825 1 (2001).

All laser sources comply with 21 CFR

1040.10 except for deviations pursu-

ant to Laser Notice No. 50, dated

2001-July-26.
