PERATION

Signal modulation

Modulation frequencies provided by the ORL-55:

• CW (Continuous Wave): without modulation
• 270 Hz modulation
• 1 kHz modulation
• 2 kHz modulation

To select a modulation frequency

Modulation can not be selected, when Auto-

 is acti-

vated. Thus, first switch off Auto-

 (see 

„Auto-

Lambda” on page 28

 ).

1. Select 

Select Modulation.

The SOURCE MOD menu opens:

2. Highlight desired frequency and press 

[MENU ENTER]

.

Adjusting the output power level

The output power level

• can be adjusted for each wavelength separately,
• can be adjusted while laser is switched on or off,
• is stored when changing the wavelength or when 

powering off.

Output power ranges

CW mode:

-3 to -10 dBm

1)

-6 to -13 dBm for 1490 nm

1) Only 1310 nm, 1550 nm and 1625 nm. 

Modulated and Auto 

:

-6 to -13 dBm

1)

-9 to -16 dBm for 1490 nm
