The 5425 contains a field proven off the shelf ILT plasma tube designed to operate in TEMoo mode and provide a polarized output beam. This model has a standard 25mW multiline output with light control feedback regulation or may be equipped with ILT’s optional littrow prism. This option will allow this end user to tune the laser from 457nm to 514nm and will guarantee 100% spectral purity.
The ILT plasma tube is constructed of BeO ceramic with enlarged metal end shrouds. This provided high thermal conductivity and large gas volume for extended tube lifetime. This tube is designed with Brewster windows sealed on each end and external mirrors, proving high polarization and high spectral purity when used with our littrow prism option. This design also gives the end-user a simple and less expensive, typical half the cost, tube to refurbish when this time comes.
The plasma tube is housed in a lightweight aluminum resonator structure which utilizes a four invar rod design. This design provides excellent mechanical and beam pointsing stability. The mirror mounts are held in place with a one piece, solid spring steel adjustment gimble. This unique combination provides field proven, hands free operation. The resonator also incorporates a molecular sieve dryer system attached to Teflon tube to mirror seals which provides guaranteed maintenance free operation.
Laser head cooling is accomplished by using a high volume fan located above the tube on the resonator cover. Air moves across the anode and cathode shrouds and exits through a fully brazed pure copper heat sink.
A fan thermostat controls cooling fans and monitors tube temperature. Fans turn on when tube is up to operating temperature turn off only after tube is completely cooled down. As a result, the tube can warm up and cool down faster.
The laser head is powered by the Model 5400 or optional 5401, high efficiency, switching regulator power supply. These power supplies incorporate a MOSFET switching bridge and high frequency isolation transformer.
