A​​ study​​ by​​ Ido​​ Kaminer​​ of​​ the​​ Technion​​ showed​​ that​​ quantum​​ mechanics​​ is​​ important​​ in​​ understanding​​ Chernkov​​ radiation.​​ This​​ type​​ of​​ radiation​​ causes​​ nuclear​​ reactors​​ to​​ glow.​​ Articles​​ in​​ Haaretz​​ and​​ Nature.​​ 

The​​ equipment​​ in​​ in​​ the​​ lab​​ includes​​ products​​ from Light​​ Conversion​​ (laser and OPA).

 

Laser​​ Quantum​​ explains​​ the​​ basic​​ principles​​ of​​ continuous​​ wave​​ (CW)​​ laser​​ technology​​ in​​ a​​ post.

Laser​​ Quantum is​​ an​​ industry​​ leading​​ developer​​ of​​ high​​ quality,​​ solid-state​​ lasers,​​ designed​​ with​​ end​​ users​​ in​​ mind.​​ Their​​ systems​​ are​​ based​​ on​​ a​​ commitment​​ to​​ performance​​ excellence​​ over​​ extended​​ life​​ cycles​​ and​​ rugged​​ conditions.

What​​ parameters​​ should​​ be​​ considered​​ when​​ choosing​​ a​​ laser​​ for​​ Raman​​ spectroscopy:

  • Excitation​​ wavelength

  • Raman​​ intensity

  • Fluorescence​​ background

 

Laser​​ Quantum offers​​ a​​ series​​ of​​ lasers​​ suitable​​ for​​ Raman​​ spectroscopy​​ light​​ sources.​​ Their ventus​​ 532​​ is​​ unrivalled​​ in​​ terms​​ of​​ its​​ size-to-power​​ ratio.​​ This​​ is​​ their​​ most​​ compact​​ 532​​ nm​​ laser,​​ and​​ it​​ is​​ optimized​​ for​​ success​​ in​​ the​​ scientific​​ industry.

Avia​​ laser​​ from​​ Coherent:

  • 266​​ nm

Optics

The​​ DeepCleave​​ module​​ from​​ Holo/Or​​ is​​ a complete​​ optical​​ solution for​​ cutting​​ applications.​​ There​​ is​​ no​​ need​​ for​​ additional​​ high​​ NA​​ objectives​​ or​​ other​​ high​​ cost​​ optics.

Reasons​​ to​​ choose​​ DeepCleave​​ for​​ your​​ gas​​ cutting​​ application​​ include:

  • Full​​ depth​​ glass​​ cut​​ from​​ single​​ pulse

  • Complete​​ solution​​ in​​ a​​ single​​ module

  • Very​​ low​​ aberrations​​ level-​​ spot​​ diameter​​ <​​ 2​​ µm

  • Easy​​ to​​ integrate​​ into​​ existing​​ opto-mechanics

Manx​​ Precision​​ Optics​​ (MPO) has​​ released​​ a​​ new​​ white​​ paper​​ discussing​​ ultrafast​​ mirrors​​ for​​ femtosecond​​ laser​​ systems.​​ Ultrafast​​ systems​​ require​​ low​​ group​​ delay​​ dispersion​​ (GDD)​​ components​​ to​​ access​​ and​​ maintain​​ femtosecond​​ pulse​​ durations

Holo/Or​​ explains​​ how​​ diffractive​​ optical​​ lenses​​ work​​ by​​ using​​ the​​ wave​​ nature​​ of​​ light,​​ modifying​​ the​​ phase​​ of​​ the​​ propagating​​ light​​ by​​ slowing​​ it​​ down​​ in​​ some​​ areas​​ of​​ the​​ beam​​ vs.​​ others,​​ thus​​ shaping​​ the​​ light​​ using​​ diffraction​​ effects.

A​​ DOE​​ changes​​ the​​ phase​​ of​​ the​​ light​​ propagated​​ through​​ it​​ by​​ using​​ micro-structure​​ patterns​​ fabricated​​ onto​​ the​​ substrate​​ material.​​ Light​​ that​​ passes​​ through​​ the​​ sunken​​ areas​​ in​​ the​​ element​​ moves​​ faster​​ than​​ light​​ that​​ traverses​​ the​​ higher​​ areas​​ (since​​ light’s​​ speed​​ in​​ air​​ is​​ faster​​ than​​ in​​ the​​ material),​​ creating​​ a​​ controlled​​ phase​​ delay.
