Products : Heat sinks for laser systems
Ceramic components offer significant advantages over metal and polymeric parts in laser systems.
When adequately designed and machined they perform as excellent long-life and reliable heat sinks for passively-cooled high power laser diode modules.
Applications
Ceramic heat sinks - AlN and alumina - are ideal to be used as electrical insulators and dissipate heat generated by components in the following applications :
- passively-cooled high-power laser diode stacks
- diode lasers
- semiconductor lasers
- fibre lasers
Products
Mirocertec offer the following customised components :
Flat heat sinks
- very thin flat substrates : 100 µm to 200 µm with thickness tolerance and flatness of 5 to 10 µm
- flat substrates in standard thickness : 300 to 600 µm with thickness tolerance and flatness of 5 µm or better
- flat substrates with grooves : 150 µm-wide minimum with a pitch tolerance of 5 µm
- flat substrates with holes and thin wall thickness hole-to- edge : down to 200 µm
Customised heat sinks
- machined heat sinks with peculiar shapes
Materials
For these heat sinks we mainly use the following advanced ceramics :
- sintered aluminium nitride – AlN – due to its higher thermal dissipation but still offering perfect electrical insulation
- alumina - aluminium oxyde - for applications where electrical insulation is solely required
Thin-film metallising
Thin-film metallised layers made under vacuum can be deposited on these ceramic heat sinks and electrical insulators in addition to our precision grinding.
Microcertec can offer the following thin-film metallised layers for your components to be bonded or brazed :
- titanium - platinum – gold
- chromium - nickel - gold
- copper, aluminium, silver, or indium
- resistive layers - Ta2N
These thin-film metallised layers can be uniquely made on 3D components. They can be ablated afterwards by laser micro-machining in order to create electrical paths or insulating areas.
