Yb:YAG's advantage is a wide pump band and an excellent emission
cross section. It is ideal for diode pumping. The broad absorption band
enables Yb:YAG to maintain uninterrupted pump efficiency across the
typical thermal shift of diode output. High efficiency means a
relatively small dimension Yb:YAG laser crystal will produce high power
output. Based on the YAG host crystal, Yb:YAG can be quickly integrated
into the laser design process.

Ytterbium Doped Yttrium Aluminum Garnet (Yb:YAG) is more suitable for diode-pumping than the traditional Nd-doped laser crystal. Compared with the commonly used Nd:YAG, Yb:YAG has the following advantages: three to four times lower thermal loading per unit pump power and much larger absorption bandwidth to reduce thermal management requirements for diode lasers, longer upper-laser level lifetime.

Tm3+:YLF crystal has a high absorption peak around 792 nm which locates in the diode pumping range, and also has a cross-relaxation process that provides the possibility for each absorbed pump photon to produce to ions at higher laser energy level. Tm3+: YLF laser is very suitable as a pump source for Ho3+:YAG laser. This is due to the good overlap of the emission band of Tm3+:YLF and the absorption band of Ho3+:YAG, and the ability to produce a linearly polarized output.

Dye Laser Handpiece are devices that screw onto the end of the laser's arm and convert the energy that the laser produces into different, new wavelengths of light.The two most common dye handpiece wavelengths are 585 nm and 650 nm,
which attach to Q-switched Nd:YAG lasers. For these wavelengths to be
produced, the Nd:YAG's 1064 nm wavelength is frequency-doubled to
produce the 532 nm wavelength, which is then converted by the dye
handpieces to produce either 585 nm or 650 nm. WISOPTIC use in-house made dye laser cells to make dye laser handpieces.
