Off-the-shelf Cavity Enhanced Optics and Electronics

 

Photop Technology now offer a series of high quality optics and electronics for cavity enhanced experiments,e.g. cavity ring-downspectroscopy (CRDS), integrated-cavity-outputspectroscopy(ICOS). 

Here, we supply parts such as high finesee mirrors with low scattering loss, high gain TIA detectors, function generator electronics that are used in wavelength scanning and ramping, and wavelength locking systems for stablizing wavelength of DFB lasers.

Most items are available from stock and ready to ship to you nextday.

 

Below you will find the list of our stock ultrafast optics and crystals, and the specsheet and prices are available online or from our sales.
