Description

High power diode laser PUMPING HEADS for solid-state laser.
PPP: pumping power | MMM: operation mode | CW or QCW | LC: laser crystal included optional.
Water cooled mount - No micro-channels are used.
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 selffocusing appears.

Main
Features

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 m
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 –60ºC to + 85ºC.
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)
Scientific (fluid dynamics, laser spectroscopy)
