Multi-photon confocal microscopy was performed by using a femtosecond
Cr:forsterite laser. Taking advantage of its unique wavelength emitting at
1200-1250 nm, high penetration depth and excellent multi-photon luminescence can
be easily observed in most bio-tissues and labeling dyes.

Large third harmonic generation was observed in bulk GaN by using an
infrared femtosecond Cr:forsterite laser. Taking advantage of this pronounced
nonlinear optical effect, we have demonstrated third harmonic generation
microscopy in GaN, which reveals interesting information not obtained before.
