Lasers & Sources

Inside of an older Spectra-Physics laser, a Triton, which has a doubling crystal, the source of the green light. It also has a tripling crystal for UV light.

After 40 years of the ‘green problem,’ the quiet laser explains itself

Intracavity-doubled green lasers within thousands of laboratories have been quiet for years without anyone knowing why. The answer is the opposite of the obvious one: A nonlinear...

FIGURE 1. Transmitted power at the target as a function of depth in tissue for a 780-nm CW diode laser (250 mW), measured in vivo through human skin and muscle for four treated-zone diameters (Ø 40, 20, 10, and 2 mm), illustrating the near-exponential attenuation of laser energy with penetration depth (unpublished data).
