Section 2..1: Diode Pumped Lasers Overview - Columbia University
The average power is about 100W/cm 2, peak power 1kW/cm 2.. The diode lasers are normally cooled by thermoelectric cooler for low power systems, and by liquid cooling for high powers.. Cooling can stabilize the diode laser frequency.. There are basically two types of pump geometry, longitudinal pumping (pump beam enters the laser medium along the ..
