Then plane reflection blazed gratings are discussed theoretically.

The optical readout color infrared imaging based on a blaze grating operates on the principle of highly efficient color seperation.

It is constructed with a semiconductor laser, collimation system, a blaze grating, and current and temperature control systems.

We have done frequencytuning experiment with the second order diffraction of the glaring grating,and observed three lines nearby 5.

A composite resonator including glaring grating is introduced for CO laser.
