High power single mode radiation by narrowband amplification of a diode laser
- A laser system is described which uses a modeless laser as a narrowband amplifier to pulse amplify the output of a c.w. single mode diode laser. A power gain of 108 was observed leading to output pulses of 120 kW peak power at 10 Hz repetition rate. The pulse amplified linewidth was measured to be less than 330 MHz. The extension of the system to produce higher powers and other wavelengths is briefly discussed.
