PH-900-QCW-YAG4

Description

Pump Laser Diode Head with Laser Crystal Nd:YAG of 04mm, pumping with 900W-QCW, water cooling,

54x56mm. More than 300W-QCW @ 1064nm. Low thermal lens model.

Main

Features

This compact laser pumping head consists of six water-cooled diode laser bars arranged radially around a

central cavity suitable for accommodating a crystal laser rod as Nd:YAG. It shows excellent gain uniformity

and lensing performance.

We have more than 10 years of experience with this product. We have combined the best high power laser

diodes with a smart design optimizing efficiency, beam quality and lifetime, as well as reducing the cost. Our

customers are very satisfied with its superior features and reliability, which help them gain competitive

advantages.

The laser module is an OEM CYLINDRICAL block. This allows rotation of the pumping chamber, thus giving

flexibility during the production and optimization of a laser system.

With a pumped length of 23mm the laser rod is shorter than other similar products in the market. This is

advantageous for regenerative amplifiers, since higher energy is available before self-focusing appears.

The pumping laser diode bars are mounted using our clamping technology. The main features of the solder-

free concept of the clamping technology, exclusively used by monocrom, are:

• Long lifetime, due to the lack of the mechanical stress caused by the soldering process at high

temperature.

• Minimum "smile", less than 0.5 |im

• High reliability in pulsed conditions, since the clamped bars do not suffer the same fatigue effect

than the soldered ones due to the thermal cycle.

• Small thermal resistance, owing the reduction of the contact resistance between electrodes and

laser bar. No micro channels are needed to reach low thermal resistances.

• Large storage temperature interval tested from -60°C to + 85°C.

Monocrom active cooled mounts use millimetre-water channels instead of micro-channels.

TAP WATER CAN BE USED FOR COOLING, without any obstruction or channel degradation.

Some

Applications

It is designed for scientific and industrial applications. For example:

• Laser marking

• Micro-machining

• Manufacturing

# Regenerative amplifiers

• Medical and aesthetical (ophtalmology, oncology, cosmetic medicine, dentistry laser)
