Abstract:

The feasibility of a flash lamp pumped, near infrared dye laser operating at a moderate repetition rate was shown. The laser produced output pulses of 17 kw peak power at a rate of 4 pulses per minute. The flow system that is essential for multiflash operation was capable of flow rates up to 50 ccsecond without degrading the output pulses this flow rate would be adequate for operation at 10 flashes per second. The excitation source for this laser is a 20 torr N2 flash lamp with a 15 cm arc length and 3mm bore. It is powered by a 0.3 microfarad capacitor at an input energy of 86 joules. The laser produced in this project would be useful in applications requiring a few milliwatts of average power.
