Abstract
A simple optical amplification system is introduced to improve the sen sitivity of both the photothermal deflection detection scheme and the surface thermal lensing technique. Parameter studies show that by choo sing an appropriate experimental arrangement the signal can be easily amplified by more than an order of magnitude.
