The difference of micro channel diode laser and macro channel diode laser
Micro channel is a kind of diode laser bar heat disappation way. It is like a man lying dowm on the ice with full body surface to cooling down.You can see from the following micro channel heat-sink.There are several layers of holes to make the heat disappation.So with micro channel way, the diode laser stack can work well and no any burning problems. Usually we imported this kind of heat sink from Germany with good quality and the water way with high precision.But also some China supplier used cheap quality immitated micro channel.And feedback not good.
