EU DECLARATION OF CONFORMITY PAGE EU Declaration of Conformity Declaration of Conformity Laser Quantum declares that the product: Name: ventus Description: 532 nm, 561 nm, 660 nm 671 nm DPSS laser has been manufactured in conformity with the following standards: •...
INTRODUCTION PAGE Introduction The ventus is a Diode-Pumped Solid-State (DPSS) laser system emitting light in the visible region of the spectrum at 532 nm, 561 nm, 660 nm or 671 nm, depending on the variant ordered. It is a Class 3b or Class 4 laser product. This manual describes the set-up requirements and operational procedures to ensure safe operation of the system.
PAGE The ventus is a Class 3b or Class 4 laser product, this is denoted by the laser warning label affixed to the laser head. A further label also appears adjacent to the laser aperture. A further label also appears adjacent to the laser aperture: When operating the laser, those in the environment must adhere to the following instructions to avoid eye damage and prevent the risk of fire: •...

SYSTEM SPECIFICATIONS PAGE A full list of parts supplied with the laser systems appear in Section 3 along with the dimensions (mm) and weights (kg). These measurements should be referred to whilst integrating the system. Parts List The ventus laser system comes complete with: •...
LASER OPERATION PAGE Figure 4-1 Figure 4-2 Warning: Serious Personal Injury The Ventus laser contains components which can be damaged if exposed to an electro-static discharge. Ensure the connector pins on the back of the laser head are never exposed to an electro-static discharge. Laser Operation...

LASER OPERATION PAGE The ventus system behaves as a travelling-wave cavity which ensures inherent single-longitudinal mode (SLM) operation. The resultant single mode is actively locked to the peak of the gain profile using a locking process within the cavity and feedback electronics in the power supply; such action maintains the single mode in its optimum frequency position.

LASER OPERATION PAGE Current Mode (where available) The pump diode current as selected by the operator is a percentage of the total pump diode current available. The requested current remains constant, however the power may drift due to environmental changes. Switching the laser “off”...

LASER OPERATION PAGE RS232 Port – Serial Commands Serial Command Function Disables the laser, regardless of the interlock status Enables the laser subject to Interlock and Enable Switch status CONTROL=CURRENT Sets the Current mode on CONTROL=POWER Sets the Power mode on This sets the current to the diodes as a % of the maximum e.g.
COOLING REQUIREMENTS AND POWER CONSUMPTION PAGE RemoteApp Using Laser Quantum’s unique RemoteApp software suite the laser can be controlled via the RS232 port. The application is supplied on a USB Flash Drive and should install automatically. Alternatively it can be downloaded from www.novantaphotonics.com.
POWER CONSUMPTION PAGE If de-rating is enabled the current will gradually be reduced to zero in order to try to allow the laser head temperature to stabilise. If the current does reach zero the system will need to be restarted. The effects of de-rating are shown in the table below: Colour of Laser and PSU text Current Laser...
LASER MAINTENANCE PAGE Laser Maintenance If the ventus is operated in a smoky or dirty environment, occasional cleaning of the laser window may be necessary. To perform this procedure, the laser must be turned off and, using optical cloth dampened with research grade methanol, the laser window must be gently wiped.
