Laser Launchers & Components

ISS offers a variety of laser launchers accommodating lasers made by ISS, Lasos, Coherent and other manufacturers. The laser launchers, with automation controlled through the computer, is used on the ISS microscopy systems and can be used to bring the light beam to any commercial laser scanning microscope or spectrometer. The main features include:

  • Each laser mounted on the launcher can be turned ON/OFF independently.
  • A shutter in front of each laser allows for selection of the laser light beam wavelength reaching the sample through the software
  • Regulation of each laser intensity is through a variable attenuator controlled by the software
  • The laser launcher controls are through the USB port.

The laser launcher includes an array of dichroic mirrors for the alignment and superposition of the lasers beams; the resulting output beams are focused onto a single-mode fiber, which brings the light beam to the microscope. If lasers for VIS and NIR regions are used, the output is through two separate fibers ((3.5 µm diameter for the VIS light; 7.5 Ám for the NIR light). The ISS launchers utilize the KineFLEX™ fibers coupler system and fibers made by Qioptiq (Excelitas Technology) to bring the light beams to the microscope. The fiber features collimator lenses permanently attached to the input and output; the lens and the fiber are assembled in a cylindrical adapter that is inserted into a fiber manipulator attached to the laser launcher for easy alignment. As the standard length of the fiber is 2m, the laser launcher can be positioned away from the microscope surface table.

A460 - 3-laser Launcher

Lasers that can be accommodated in this unit include:

  • Laser Diodes made by ISS, Lasos
  • DSSP Solid State lasers made by Coherent

When using the nanosecond-pulsed lasers by ISS, the driving signal for the lasers is
controlled by an amplifier mounted in the launcher.

A461 - 4-laser Launcher

Lasers that can be accommodated in this unit include:

  • Laser Diodes made by ISS, Lasos
  • DSSP Solid State lasers made by Coherent

When using the nanosecond-pulsed lasers by ISS, the driving signal for the lasers is
controlled by an amplifier mounted in the launcher.

For FLIM measurements using the DSSP lasers a Pockels cell, mounted into the
launcher, is used as a pulser.

Intensity Control of Ti:Sapphire Laser

The Intensity Controller allows for the control of laser power diverted into the microscope. The beam from the laser goes through a rotating half-wave plate and a Glan-laser calcite polarizer. The intensity of the output beam is regulated by rotating the half-wave plate.The rejected portion of the beam is absorbed by a beam dumper. The unit is connected through the USB port.
