In this work we design and construct a pulse compressor with volume transmission holographic gratings, to compensate
the second order dispersion in femtosecond laser pulses emitting at 794 nm with a spectral broadband of 10 nm. The
gratings (730 lines/mm) are recorded in PFG-04 dichromated gelatine emulsion with a wavelength of 532 nm, reaching
enough index modulation to use the gratings illuminated with 800 nm light source with high efficiency (around 80% of
efficiency in each grating). This efficiency is expected to be increased with an antireflection coating. We measure the
factor of compression as a function of the grating distance using an autocorrelator, finding a good agreement with
theoretical curve. A dispersed pulse (580 fs) is reduced to the bandwidth limited value of 106 fs with the grating pair
separated by 27 mm.
In this work we applied the Gagne instructional model to the design and development of a JAVA web page by teaching and learning of the basic physics of the color address to undergraduates optics courses. The color simulations were development interactive and friendly for running at different operative systems. The pages were structured in two parts: (1) Theory: Color, Physics of color, Digital Color; (2) Practice, Simulation of additive mixture, color models, color matching and separation mechanism. The page includes links to specialized sites. The instructional design was validated using experts criteria and tested with learners of third years optics course at the Universidad De Carabobo.
