Diode lasers

The LSM 880 can be equipped with Diode 440

and / or Diode 405 lasers that can be used in
continuous wavelength (cw) mode or in pulsed (ps)

mode (Fig. 88).
Selection of the mode is available in the Mode
pull down menu in the

Laser properties

menu

(Fig. 89).
You can select between

Continuous Wave

or

Pulsed - 20 MHz,

Pulsed - 50 MHz

and

Pulsed -

80 MHz

mode.

The diode lasers are directly modulated. They can
be further attenuated once a pulse frequency is
selected by ticking the

ND04

check box, which will

place a neutral density filter in front of the lasers.
Please note that pulsed modes were specifically

designed for Fluorescence Lifetime Microscopy
(FLIM) and should be preferentially used for this

application. Since laser powers in the pulsed mode
are substantially less than in the cw mode, the

pulsed mode is not suitable for bleaching
experiments. Also signal-to-noise ratios in intensity

imaging are less in the pulsed mode compared to

cw operation, hence the cw mode should be
chosen for high quality imaging.

Argon laser

The Argon laser is a gas laser that is operated in a slightly different way compared to the other lasers. It
needs some minutes to ignite and warm up and, being air cooled, needs also some minutes to cool down

after it has been switched off. The lifetime is dependent on the the operation mode and messages are
provided to help you run it in its optimal mode for maximum lifetime. The laser is integrated in the SW

similar to other lasers. Until the laser is in standby mode it does not produce a constant power output.

The current status of the laser is indicated at any time during the operation of the system in the Laser
Properties panel of the

Laser

tool window.

Operation of the Argon laser:

1.

The laser power supply is linked to the main power switch: Upon switching on the main power of

the system, the laser is supplied with electrical power which is linked to the permanent cooling of

the laser. The power switch on the laser module itself has to be switched on. The key switch of
the laser has to be set to 1 to be able to control the laser via SW.

2.

When starting the Software and opening the Laser tool window the laser can be in three states:

a. In case the laser is set to Off via the power switch on the laser power supply, the system SW

provides a time out error with the message: "Hardware Argon Laser not found. Please check
the main switch on the laser electronics." The status report in the Laser Properties panel of
the Laser tool window shows the status

Not connected

.

-> In this case turn the power switch of the laser power supply to On.
