A dental laser system (12) is configured to provide high peak laser power, low duty cycle laser pulses, yielding a low average laser power and thus a reduced need for cooling. The laser power system may be configured to provide the electrical power required to produce the low average laser power and not the high peak laser power, and may include a capacitor bank section having at least one capacitor (50) configured to provide the electrical power needed to produce the high peak power laser pulses. The capacitors (50) are charged by a power supply comprising an AC filter (42) for removing noise and an AC-DC converter (44) charging the capacitors. At least 75% of the electrical power supplied to the laser should be delivered by the capacitors, the remainder directly from the AC-DC converter. The electrical power is supplied to the laser (12) by twisted lines (52,54) in order to reduce noise. The cooling system may be configured to provide laser cooling for the low average power level and thus may not require a refrigeration unit.
