Interfering the laser pump
light and returned SBS light can provide a heterodyne measurement of the frequency shift, which makes it possible to compare images, monitoring different mechanical properties.
In order to monitor the temporal profiles of the LIF and ASE from the 560 nm QD laser pumped
by a 3rd harmonic (355 nm, 10 Hz) nanosecond laser, the output emission was transmitted to a UPD connected to an oscilloscope with the trigger signal being acquired from the Q switch out of the pump laser.

by a 700-1050 nm Vertical Cavity Surface Emitting Laser," US Patent 5754578, May 1998.
The C5L is a combo light and laser, providing you with a l00-lumen light and a green laser pumped
up to the maximum allowed by federal regs.
Extreme utility of this laser is key to the development of tunable, direct-diode laser pumped
dye liquid lasers operating in the blue or blue-green wavelengths, as well as the 550 to 620 nm wavelength region.
In some cases, when the wavelength of the excitation pulse is not adapted to the requirements of a specific experiment, a laser pumped
dye laser is employed.
Compared with OPA, near-infrared laser pumped
OPCPA is more promising for producing high-energy midinfrared lasers without causing significant nonlinear pulse distortion or causing damage.
