| Thermal effects vs. gain in femtosecond laser written waveguides in neodymium doped fused silica (2006) | |||||||||
Abstract | |||||||||
| The influence of thermal effects in gain measurements of fs laser-written waveguides in actively doped glass is reported for the first time. We show that these effects strongly contribute to the signal enhancement (up to 50% observed). Thus, a new measurement scheme to distinguish between thermal induced signal increase and real amplification is proposed. | |||||||||
