Continuum Surelight II-10 Q-switched 4-6 ns Nd:YAG laser operating at 1064, 532, 355 and 266 nm with the repetition rate of 1 - 10 Hz. 
 
Injection Seeder system for Continuum Surelite laser. Seeding produces an ultra-narrow single longitudinal mode output with a smooth temporal profile from the laser. 

 

Spectra Physics Navigator DPSS laser delivers high intensity 1064nm and 532 nm pulses with the  wide range of pulse widths (70-110 ns) and repetitions rates (1- 30 kHz).
 

Major Lab Instrumentation

 
Sandercock scanning 6-pass tandem Fabry-Perot interferometer is employed to measure Brillouin light scattering in various materials to study their viscoelastic properties. The technique is based on the interaction of CW laser photons with the fundamental matter excitations such as GHz acoustic phonons.
