Laser Launchers & Components

ISS offers a variety of laser launchers to accommodate lasers of various sizes and shapes. Each laser launcher can accommodate up to four lasers. Each laser can be turned on or off independently.

A variable attenuator for regulation of the laser intensity and a shutter are mounted in front of each laser diode for controlling the relative intensity delivered to the microscope. The lasers beams are aligned and superimposed using dichroic mirrors and focused onto a single-mode fiber (3.5 μm diameter) which brings the light beam to the microscope.

The ISS launcher uses the KineFLEX™ fibers coupler system and fibers made by Point Source Ltd. (United Kingdom). The fibers feature 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.

Laser Launcher for Laser Diodes

This unit accommodates up to four lasers diodes that can be utilized simultaneously or one at a time. Radio frequency can be injected into the laser launcher for modulation of the lasers intensity up to 500 MHz.

Hybrid Laser Launcher

The Hybrid Laser Launcher accommodates one argon-ion laser, two HeNe laser and one laser diode or solid-state laser. For applications requiring the modulation of a light beam, an electro-optics modulator is mounted in the laser launcher.

Lasers that can be accommodated in this unit include:
•   Ar1 Laser
•   HeNe
•   DSSP Solid State lasers (488nm, 532nm, 594nm)
•   Laser Diodes (370nm, 405nm, 440nm, 473nm, 488nm, 635nm, 660nm)

The Hybrid Laser Launcher is self-contained and its operations are controlled through the USB port of a computer. The unit also includes a general power supply.

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.

Computer-controlled Beam Steering Device

An automated beam steering device allows for control of the laser alignment through the computer. Stepper motors are mounted on each mirror and allow for fine control of the azimuthal angle. Ultra fast mirrors (with low GVD) are mounted.
