Product Overview

This section provides an overview of High Power Laser Engine models.

HLE Front Panel

High Power Laser Engine front panel.

HLE-FL1 Switch

The HLE-FL1 controller switch turns OFF the electrical power to the HLE-FL1 fibre laser (LM-HLE-560-1000). This laser will run continuously when the power is on, so it is advisable to turn it off when not in use.

Output Couplers

Laser is emitted from the unit via the output couplers. A single output is standard but dual outputand triple outputs are available. They couple the internal laser outputs into MM fibre(s) attached depending on the requirements for the specific system configuration. A locking mechanism is provided for each of the outputs. This protects each fibre from disconnection from its output coupler.

Warning
Never remove the fibre lock when in operation. The cable should only be disconnected by qualified service personnel. A tool is required to open the locking mechanism once closed.

Laser Power Key Switch

The Laser Power Key Switch on the front panel of the High Power Laser Engine disconnects electrical power to all the lasers via a control circuit if it is in the OFF position, except for the HLE-FL1 fibre laser (if present) which has its own switch (HLE-FL1 Switch).

The Laser Power Key Switch does not turn off the temperature control of the lasers to allow them to remain stable, except for OBIS lasers (LM-HLE-561-150/ LM-HLE-594-100). Also, if the Laser Power Key Switch is in the OFF position the HLE primary shutter is closed, which blocks all laser emission from the HLE unit, which means that even if the HLE-FL1 laser is turned-on it cannot emit from the HLE unit.

The key cannot be removed when the switch is in the ON position, but it can be removed when the switch is in the OFF position.

System Power and Emission Enabled Indicator LEDs

The upper green system power indicator LEDs light when the rear panel mains rocker switch is turned ON. The internal AC/DC power supply is receiving power from the mains power supply.

System power indicator LEDs and emission enabled indicator LEDs

The upper red LED is turned ON a few moments after the Laser Power Key Switch is turned on. The lower red LED is turned ON when the primary shutter is opened a few seconds after the laser power is turned on. This indicates that laser emission is possible and could be imminent. Both red LEDs are turned off if the interlock is open (See “Remote Interlock). Note that there are two LEDs for redundancy, in case one fails. If one LED fails, notify Andor Service.

Power Monitor Cover

The power monitor is only accessible to service personnel and not accessible to users.

Optical Input (Blanked)

Not used on High Power Laser Engine.
