Operating your Tunable Laser Source

42 FLS-2600B

Activating/Deactivating Light Emission

Before turning on the Tunable Laser Source, please read the Safety

Information on page 7.

If the source has been exposed to extreme conditions or if you feel that a

calibration would help you achieve better results, you can perform an

offset calibration as described in Adjusting Your Unit According to

Wavelength on page 54.

To activate or deactivate the light emission:

1. Press the On/Off button. The Source init. marker appears on the

display.

2. The Active LED lights up on the module front panel to indicate that the

source is active at the wavelength, output power, and mode currently

selected.

3. To deactivate the source, press On/Off again.

IMPORTANT

The Active LED usually lights up immediately, but the laser power is

ramped to its maximum in about five seconds. If an error occured

with the power prior to the source initialization, the active LED can

take up to three seconds to light up.

IMPORTANT

To obtain optimum stability, a laser source should be allowed to

warm up for 60 minutes.
