Title: Frequency stabilized light source
Inventor: SAITO TAKANORI
IPC: H01S5/00
Filed: 1991-03-15
Abstract: PURPOSE:To stabilize the frequency of laser light to the Lamb dip of the light absorption line of atoms or molecules by modulating the laser light by using the Doppler effect. CONSTITUTION:The lamb dip of laser light from a semiconductor laser 1 can be observed from the intensity of the reflected light of the laser light by perpendicularly reflecting the laser light by means of a reflecting mirror 7 after the laser light is passed through an absorption cell 6 in which atoms or molecules are enclosed and again passing the reflected light through the cell 6. Since the frequency of the reflected laser light is modulated by a Doppler effect when the reflecting mirror 7 is vibrated, the differentiated waveform of the Lamb dip can be obtained when phase detection is performed on the intensity of the reflected laser light by using the frequency of the vibration of the mirror 7. The frequency of the laser light is stabilized to the peak frequency of the Lamb dip by feeding back the phase-detected output to a semiconductor laser controlling current source 12 as a frequency discriminating signal.

Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which the diameter of a circular tube can be measured in a noncontact manner-even in a comparatively inferior environment by a method wherein resonance frequencies in an m-th order mode are found with reference to three kinds of axially symmetric SH waves whose node numbers are different on the whole circumference of the circular tube, the resonance frequencies are substituted into a specific expression and simultaneous equations which are composed of three specific expressions are solved. SOLUTION: Resonance frequencies f1, f2, f3 in an m-th order mode are found with reference to three kinds of axially symmetric SH waves which have different node numbers N1, N2, N3 on the whole circumference of a circular tube. The three resonance frequencies are substitued into an expression (a frequency equation), three simultaneous equations are solved, and an outside radius (a) and an inside radius (b) are found. In the expression, (c) represents the sound velocity of SH waves, (n) represents an order corresponding to a node number, ωm <(n)> represents a resonance frequency in an m-th order mode and an angular frequency which is found so as to correspond to the order (n), and Jn and Yn represent a first-order Bessel function and a second-order Bessel function corresponding to the order (n).  In order to find the resonance frequencies, it is preferable to use three kinds of ring-shaped electromagnetic ultrasonic transducers in which the number of permanent magnet members is different.

Title: Solid laser oscillator
Inventor: YOSHIDA KUNIO
IPC: H01S3/093
Filed: 1993-03-10
Abstract: PURPOSE:To increase the quantity of pumping light by placing first and second pumping means so that they face one surface of a solid laser medium, and placing a shield board between both light pumping means to reflect the pumping light emitted from both optical pumping means to the one surface side of the solid laser medium. CONSTITUTION:A shield board 5 is provided between two flash lamps 1 and 2. The shield board 5 is made of a material opaque to pumping lights L1 and L2, and reflects the pumping light incident upon the shield board 5 to the underside 4 of a laser medium 3 without transmitting them. Consequently, the pumping lights L1' and L2' reflected by the shield board 5 are caused to be directly incident into the laser medium 3 and absorbed. Thus, since not only the pumping lights L1 and L2 directly incident from the respective flash lamps 1 and 2, but also the pumping lights L1' and L2' which will otherwise enter the other flash lamp, respectively, are used, the pumping efficiency can noticeably increased.
