High performance

liquid coolers for laser

diode applications

Liquid coolers for high power

applications like CPU for data

centers, direct cooled power

modules, high brightness LED

or solar-cell arrays (CPV)

Passive cooling

for laser diode

applications

Rogers offers two kinds of cooling solutions –

coolers for liquid or passive cooling.

For liquid cooling Rogers offers the curamik® CoolPower and

CoolPower Plus as well as the curamik® CoolPerformance and

CoolPerformance Plus. At the heart of these liquid coolers, there

is a mircro or macro channel structure made of thin copper foils

that are put together into a hermetically tight block using the

curamik bonding process. The speciﬁc channel structure deter-

mines the thermal resistance, pressure drop and ﬂow rate. The

coolant usually enters and exits through openings connected

with o-rings or screw ﬁttings. Liquid coolers are an ideal solution

for high-power applications.

Advantages

// Four times more efﬁcient cooling than traditional

module structures with liquid cooling

// Lower weight

// Smaller sizes

The curamik® CoolEasy is a high precise machined copper cooler

for passive laser diode cooling.

curamik® CoolPerformance

curamik® CoolPerformance Plus

The curamik® CoolPerformance coolers are high perfor-

mance copper coolers for laser diode cooling. The coolers

consist of several layers of pure copper with very ﬁne

structures. These layers create three-dimensional micro- or

macro-channel structures for cooling laser diode bars up to

 mm cavity length.

curamik® CoolPerformance Plus coolers are high perfor-

mance isolated copper coolers which additionally contain

an AlN isolation layer on top and bottom. The AlN isolation

layers separate the water channels from the electrical

contact to the laser diode and reduce the CTE value of the

cooler to  – . ppm/K. The top and front surface of these

coolers can be diamond-milled to meet the exacting needs

of ﬂatness of laser diodes.

Both types of coolers can be used with high power laser

diodes in the range of  to more than  W.

Applications for these coolers are laser diode stacks which

are used in diode pumped lasers or direct diode lasers for

industrial, medical and research applications.

curamik® CoolPower

curamik® CoolPower Plus

The curamik® CoolPower consists of several layers of

pure copper with very ﬁne structures. These layers create

three-dimensional structures for cooling high-performance

electronics. During the curamik bonding process, the

different layers are hermetically combined without any

additional soldering or adhesive layers.

curamik® CoolPower Plus coolers are integrated DBC

coolers with ceramic substrates (Al





or AlN). The DBC

substrate-layers enable direct assembly of the components

(chip on board) and provide at the same time electrical

isolation from the cooling circuit.

curamik® CoolPower and curamik® CoolPower Plus are used

for the cooling of high-performance components, high

brightness LED or solar-cell arrays.

curamik® CoolEasy

curamik® CoolEasy is a high precise machined copper cooler,

which is used as CS-Mount for conductive cooling of laser

diode bars. The top and front surface of the cooler can be

diamond-milled to meet the exacting needs of ﬂatness

of laser diodes. Applications for these coolers are diode

pumped laser modules or direct diode lasers for industrial,

medical and research applications. curamik® CoolEasy

copper coolers are used with high power laser diodes in the

range of  to  W.
