“…Lutetium oxyorthosilicate (Lu 2 SiO 5 , LSO) has attracted the attention of researchers due to their favorable thermal and optical properties, which make it suitable as host materials to be used in photonics as laser media [3][4][5][6] or scintillators [7,41,59]. The main technique for producing LSO crystals is usually the CZ method.…”

“…The production of high-quality silicate-based single crystals is mainly accomplished by solid state and Czochralski methods ( [1][2][3][4][5][6][7][8][9] and references therein). However, these methods require several amounts of material and the use of crucibles that can introduce external contamination.…”

This chapter reviews the laser floating zone (LFZ) technique, also known as the laser-heated pedestal growth (LHPG), focusing on the recently produced rareearth-doped oxyorthosilicate fibers. LFZ has been revealed as a suitable prototyping technique since high-quality crystals can be developed in short time with low consumption of precursor materials in a crucible-free processing that ensures to practically avoid by-products. Moreover, additional advantages are the possibility to treat and melt highly refractory materials together with the easy way for tailoring the final microstructural characteristics and this way the macroscopic physical properties. Thus, refractory rare-earth (RE) doped oxyorthosilicates following the formula RE 2 SiO 5 have been recently produced by the LFZ technique for tuning laser emission parameters. The oxyorthosilicates have high chemical stability and allow incorporation of many rare-earth ions yielding different applications, such as laser host materials, gamma ray detectors or scintillators, environmental barrier coatings (EBCs) and waveguides, among others. Thus, different kinds of oxyorthosilicates were produced by the LFZ technique, and the detailed effects of the main processing parameters on crystal's characteristics are discussed in this chapter.

“…Currently, Yb-based femtosecond lasers delivering watt-level sub-100 fs pulses have been reported only in a few kinds of crystals such as Yb:CaF 2 [12][13][14], Yb:CGA [15][16][17], Yb:CYA [18], Yb:KGW [19][20][21], Yb:KYW [22], Yb:YVO 4 [22], and Yb:Lu 2 O 3 [23] as well as Yb:LuAG ceramic [24]. Apart these materials, the family of Yb doped oxyorthosilicates [25] (including Yb:GSO, Yb:LSO, Yb:YSO, Yb:GYSO and Yb:LYSO crystals) are also promising candidates for producing sub-100 fs pulses with watt level average power, due to their broad emission spectra as well as excellent thermal conductivities as summarized in Fig. 1.…”

We report on a Kerr-lens mode-locked Yb:YSO lasers for the first time. Pumped by a single-mode fiber laser with high brightness and linear polarization, the Yb:YSO laser can deliver as high as 2 W average power with as short as 95 fs pulse duration at the repetition rate of 137.2 MHz, resulting in the single pulse energy of 14.8 nJ and the peak power of 155.7 kW. This work proves the potential on generation of sub-100 fs pulses with multi-watt level average power with the Yb doped oxyorthosilicates crystals.

“…The Yb 3+ doped oxyorthosilicate Y 2 SiO 5 (Yb:YSO) crystal is an attractive laser material as the other Yb doped oxyorthosilicates because its admirable laser properties [35]. Firstly, the ground state energy splitting of Yb 3+ ion in Yb:YSO crystal is up to 984 cm −1 which leads to a quasi-four level operation and then a low pump threshold.…”

We experimentally demonstrate the dissipative soliton mode-locking operation of a Yb:YSO laser by using an all-normal dispersion cavity. Strongly chirped pulses are obtained with pulse duration of 9.3 ps at a repetition rate of 113.4 MHz. The central wavelength is 1082 nm with 3.1 nm FWHM bandwidth. A dual-wavelength synchronously mode-locking operation at central wavelengths of 1059.2 nm and 1082.2 nm is also reported. Stable mode-locked pulses are achieved with pulse duration of 10 ps and total average output power of 164 mW. Periodic ultrashort beat pulses with pulse duration of 169 fs at an ultrahigh repetition rate of 1.4 THz can be distinctly observed from the measured autocorrelation trace. To our knowledge, this is the first demonstration of dual-wavelength synchronously mode-locking operation from a Yb:YSO laser.
