Multiline generation capabilities of diode-pumped Nd:YAP and Nd:YAG lasers

Multiline generation capabilities of diode pumped Nd:YAP and Nd:YAG lasers within 1.3-1.5 μm wavelength range at room temperature are reported. Two optical resonators designed for 1.3 μm and 1.4 μm laser operation have been realized. Using a single quartz plate as a tuning element, six single emission lines within the 1.3 - 1.5 μm spectral range for both Nd:YAG and Nd:YAP lasers have been reached. Moreover, as also demonstrated, it was possible to obtain Nd:YAG/YAP dual frequency regime operation for some line combinations.
