“…Since 1990s, many studies of sum frequency tech nology have been carried out, and then obtained many new wavelengths, such as green laser at 538 nm, by self sum frequency mixing of both fundamental infrared laser waves (1061 and 1091 nm), with 18.2 W of diode pump power, a maximum output power of 1.73 W has been achieved [8], 531 nm, with a diode pump power of 8.3 W, laser at 531 nm of 148 mW is obtained [9], blue green laser at 497 nm, by self sum frequency generation of the 936 and 1060 nm, with a diode pump power of 14.3 W, the maximum output power was 75 mW [10], yellow laser at 592 nm, with a diode pump power of 9.8 W, laser at 592 nm of 37 mW is obtained [11], orange laser at 600 nm, by intracavity sum frequency generation of the 1085 and 1342 nm laser lines of two Nd:YVO 4 lasers, laser at 600 nm of 1.06 W is obtained. The power stability in 30 min is better than 2.8% [12], and so on.…”

An all solid state single longitudinal mode (SLM) laser at 500.8 nm with 830 mW output power has been demonstrated for the first time. By using a new resonator for doubly resonant, Nd:GdVO 4 and Nd:YAG were pumped by two laser diode arrays coupled by optical fiber, respectively. In the two sub cavities, SLM wavelengths of 1064 and 946 nm were induced by using the twisted mode technique and then mixed into SLM 500.8 nm laser with sum frequency technology. The SLM 500.8 nm laser output of 830 mW was obtained at the incident pump power of 20 W for Nd:GdVO 4 and 23 W for Nd:YAG. The experimental results showed that the intracavity sum frequency mixing by twisted mode technique is an effective method for SLM 500.8 nm laser.

“…The other way is to develop lasers emitting at the lowest wavelength possible in the near infrared [2] and to perform nonlinear conversion. Various solid lasers in blue spectra range [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] have been obtained by nonlinear conversion of the transi tion of solid lasers [18][19][20][21][22][23][24][25][26][27]. These blue lasers are effi cient and powerful, nevertheless their wavelengths are too high compared to the 442 nm He-Cd laser.…”

“…In these lasers, the key material is a self-frequency-doubling crystal which performs both functions of laser emission and nonlinear optical conversion in a single crystal. Nd or Yb doped YAB, GCOB, YCOB, MgO:LiNbO 3 , Nd:LiNbO 3 , and LnCa 4 O(BO 3 ) 3 (Ln = Y or Gd) are three most promising series selffrequency-doubling crystal [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. Nd 3+ doped GdCOB has been reported to perform very efficiently as a continuous wave (CW) self-frequency-doubled laser in the green laser radiation based on self-frequency conversion [47,48]…”

Phenyl acetic acid, a metabolite of 2—phenyl ethylamine, acts as a neuromodulator in the nigrostriatal dopaminergic pathway neuromodulator stimulating the release of dopamine. The evaluation of phenyl acetic acid concentration in the biological fluid reflects phenyl ethylamine levels thus allowing the assessment of the modulatory role of this endogenous substance. Changes in biological fluids levels of 2—phenylethylamine and/or in its metabolite have been reported in affective disorders, such as depression and schizophrenia. Recently, the occurrence of the “attention deficit hyperactivity syndrome” has been frequently reported in childhood population and involvement of dopaminergic dysfunction in this disease has been suspected. A fast, reliable and reproducible method for the determination of phenyl acetic acid in human blood, is therefore needed in order to have a screening tool for monitoring both healthy childhood population and suspected “attention deficit hyperactivity syndrome” patients. The gas chromatographicmass spectrometric method here described makes use of a deuterated internal standard in order to overcome problems related to the lack of reproducibility often encountered when a derivatization step is performed.
