Temperature-dependent wavelength shifts of dye lasing in microdroplets with a thermochromic additive
Publikováno v:
Optics letters. 20(16)
The lasing spectra from a Rhodamine B–doped microdroplet (85% isopropanol and 15% water) with a thermochromic additive (CoCl2.6H2O) have been observed to shift progressively toward blue as the droplet temperature is gradually increased. The absorpt

A 500 channel system is described for measuring time intervals up to 1 μsec in 2 nsec increments. The vernier chronotron method of Lefevre and Russell is modified by the addition of a stable time base which phase‐locks the circulation period of ea

Application of techniques previously developed by the authors for the precise measurement of excited-state lifetimes has been made to radiative and collision-induced relaxation in the ten fine-structure levels of the $2{p}^{5}3p$ configuration of ato

The real time computation of the correlation function of two signals of up to 2.5 MHz bandwidth at 30 points simultaneously has been achieved to an accuracy of better than 3% of reading ±2% of full scale by a probabilistic computational procedure. A

A helium‐neon maser of the plane parallel Fabry‐Perot type has been constructed in which both the angular adjustments and the plate separation may be controlled through magnetostrictively produced distortion in a rigid Nilvar mounting frame. The

A technique is presented for the precise measurement of the “instantaneous” carrier frequency of bat pulses. An augmented commercial frequency counter is used to measure the period (or a short‐term period average) of the bat pulse carrier. An e
