Comparison Between Conventional Light Sources and Lasers

1 Comparison Between Conventional Light Sources and Lasers 

A comparison is made in Table 9.1 between a conventional line light source and a continuous single-mode dye laser both sources with representative data. In many spectroscopic experiments a decisive factor is by what power per unit area and spectral interval a sample can be irradiated. The designation I(i ) is used for this power density/frequency unit. In the comparison in
