Verdi V-2/V-5/V-6 Laser Preinstallation Manual

Introduction

The purpose of this document is to assist the user in establishing a

suitable location and operating environment for optimum Verdi

V-2/V-5/V-6 performance.

Receiving and

Inspection

Inspect shipping containers for signs of rough handling or damage.

Indicate any such signs on the bill of lading. Report any damage

immediately to the shipping carrier, and to Coherent Order Admin-

istration Department (800-438-6323) or to an authorized Coherent

representative.

Retain shipping containers. The containers will be required if

the system is returned to the factory for service. The containers

may also be needed to support a shipping damage claim.

Coherent recommends that three people unpack and transport the

Verdi V-2/V-5/V-6. The power supply weighs70 pounds and should

be lifted by two people while the laser head, which weighs 22.2

pounds, can be lifted by the third person. The laser head and power

supply are connected by the umbilical.

Installation Kit

The installation kit contains the necessary hardware for Verdi instal-

lation. See Figure 1-1 for details.

Installing the

Laser Head

The laser head is shipped with either a passive or a water-cooled

riser/heat sink. This riser/heat sink maintains the Verdi output beam

at a suitable height for pumping a laser such as the Coherent Mira.

A passive riser/heat sink when mounted on a thermally conductive

surface (such as an optical table) provides sufficient heat dissipation

for the laser head under normal ambient conditions. The temperature

of the laser head baseplate is monitored by the Verdi power supply

and can be displayed on the power supply front panel. Power dissi-

pation through the baseplate is typically 20 to 25 Watts (30 Watts

maximum). The Verdi will shut down if the baseplate temperature

exceeds 55°C.

An optional water-cooled riser/heat sink is available for use with a

chiller.
