HPL-440-Q440 nm violet Q-switched pulsed laser
440 nmThe HPL-440-Q is a 440 nm nanosecond diode-pumped solid-state laser. Laser diodes optically pump a solid gain medium inside a resonator. The pump supplies the energy; repeated passes through the gain medium amplify the laser light. Q-switching stores energy in the gain medium while resonator losses are high, then lowers those losses to release a pulse. Pulse energy and repetition rate must be considered together, because changing the pulse spacing changes the average power for a fixed pulse energy. At the nominal 5 kHz repetition rate, pulses lasting approximately 200 ns arrive about 200 µs apart.
