TUN-TiA-770-840770 nm near-infrared tunable Q-switched pulsed laser
770 nmThe TUN-TiA-770-840 is a 770 nm nanosecond Ti:sapphire laser. An optical pump excites titanium ions in a sapphire crystal. Their broad gain spectrum allows the resonator to select and tune the output wavelength within the specified range. 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. Pulses shorter than 40 ns deliver the energy in a brief interval; pulse energy and focused spot size determine the intensity at the sample. The quoted power range represents factory-set configurations; specify the required output rating when ordering.
