A symmetric confocal resonator with mirror spacing d = 16cm,mirror reflectances 0.995, and n =1 is used in a laser operating atλo = 1μm.a) Find the radii of curvature of the mirrors.b) Find the waist of the (0,0) Gaussian) mode.c) Sketch the intensity distribution of the (1,0) modes at oneof the mirrors and determine the distance between its two peaks.d)Determine the resonance frequencies of the (0,0) and (1,0)modes.e) Assuming that losses arise only from imperfect mirrorreflectances, determine the distributed resonator loss coefficient αr
a) Design a circuit with a single opamp to realize V0=V1-4V2, where V1 and V2 are two input voltages. b) Select the resistor values so that no more than .25W is dissipated in any resistor when the input voltages are no larger than 10V
The diameter of no.12 Copper wire is 0.081in. The max. safe currentit can carry is 20 A. At this current, what is the drift velocityof the electrons (the number of electrons carries on cubiccentimeter of copper is 8.5 x 1022.)
design a circuit to sort a product which has 2 different color in two diffrenet boxes for example red and green apples no any microcontroller or microprossser are allowed. which color sensor is the best to have 5 volt output so a solenoid may work..
A 10 kW laser beam pointing at the ship is turned on at t=0. What speed the ship will attain in 1 day assuming that the surface of the ship is perfectly reflective and perpendicular tot the beam.
The transformer secondary is now connected to a purely resistive load drawing 50A. Calculate: a) the total resistance and leakage reactance values referred to the secondary (Rt2 and Xt2), b) the output voltage, c) the output power, VA and Vars,
A 65volt neon lamp is connected across a 8h coil with aresistance of 275. When the coil's field collapses, a 6k resisteris inserted into the circuit in series with the coil. The source is 25 volts D.C.
A 500 line/mm diffraction grating is illuminated by light of wavelength 510 nm. How many bright fringes are seen on a 2.0 m wide screen located 2.0 m behind the grating
The transfer equation is V_out/V_in. if you factor the second order polynomial what are the two first order polynomials. How do these compare with the first order filter. Has the -3db changed.
Given a LEO satellite system with a dish gain of 20 dB , orbiting altitude of 789 km, and download frequency of 1626 MHz , what is the satellite's transmitter output power required so that it is received by a wireless phone with 1 pW
a. Describe in your words why I_G is effectively 0A for a JFET transistor b. Why is the input impedance to a JFET so high c. Why is the terminology field effect appropriate for this important three- terminal device
consider a fax/xerox outlet, processin files of various size. the size (in number of pages) of the files to be faxed or xeroxed has a geometric (p) and poisson (a) PMFs respectively. An arbitrary file arriving at the outlet is a fax file with prob..
